How to service a mechanical watch. Part 3. AS 1900 in a Rotary watch

[@bernardrocchia9935]

I just finished my first complete watch service on my father's Tavie French watch from the 50s. I can't tell you how I felt after a successful outcome. Being that it was my father's watch made it even more incredible. I could not have done it without your incredible videos. Your generous knowledge insures that the hobby continues. I don't know if you will have time to read this message but I wanted to do my best to express my gratitude towards you. You can bet I will continue to move onward in this fascinating study. Thanks Mark, Bernard Rocchia, Franklin Park NJ

[@GDLOTKIDOG]

DUDE! What in the world HOW did you just toss the second hand on like that? I have spent 2-4 hours setting the second hand. What it easy like that because it’s an older broken in watch? Thank You so much Mark you are a great teacher.

[@GarthCHanna]

As a student of horology I found this very useful. We are taught the theory side of servicing but the practical is left to our peril, so seeing someone actually do it is very helpful and I picked up a lot of good tips. I will be recommending my class mates to check this channel out :)

[@projboss68]

Mark, thank you so much for this three-part series. I am new to horology and am nervous and uncertain about a lot of items. Seeing how you do the cleaning and listening to your key points is taking away some of my nerves around this process. I appreciate you and the way you are helping us, newbies. Keep up the great job.

[@russtbird]

This is an inspiring and informative channel and I just completed the successful repair of an AS 2063 given to me by my father many years ago based on these 3 videos. Thanks Mark and keep up the great work.

[@WilliamJPrah]

Thoroughly enjoyed the conclusion of this video series! I'm so glad you name all the parts with your narration, and explain what you are doing and why! Long time watch owner/collector, but fairly new to deeper learning on the subject.

[@WatchRepairChannel]

Thank you William.

[@rajshah7918]

I must congratulate you, for all the three videos, explanation and demonstration which is of utmost importance for repairers entering in this field. Though modern technology, arrival of quartz watches as well as digital ones, the mechanical watches will still remain dominant in this world. I too am semi efficient repairer for want of unique tools like automatic oiler, spring winder, different types of oil and use of grease etc. I am happy to say that application of oils and grease at crucial spots like pallet stones etc. is the most valuable guidance acquired from the three parts. Excellent and congratulations to you.

[@projboss68]

Great job on these videos! You made servicing my watch much easier than it would have been without your instruction.

[@wayneturner1336]

Really can’t say enough about the quality of workmanship and video. Absolutely brilliant.

[@JorgeCDiez]

Once again you gave us a lesson of how to service a watch with professional and gentle dedication...

[@whitenorthstar]

Amazing to watch! I thought I had patience working with electronics! Thanks for the videos!

[@rcastor1]

Thank you for your clear instructions for properly oiling the exit stone on the escape pallet. I followed this procedure servicing my circa 1909 Chelsea ship's bell movement which uses a Waltham watch escape. I hope to post a video of this clock soon and will reply to this comment with a link. Thanks again for your valuable contirbutions!

[@robertgoidel]

Mark, This was an excellent video of a three part presentation of your servicing this AS1900 movement. Your work form is excellent and have learned a lot from watching your videos. Keep up your wonderful work.

[@greggm1232]

This is very educational & I'm really interested in learning all I can on watch repair, especially the way he shows and explains. I'm new at doing work on watches an trying to learn how to work on watches in all phases, but really, really wanting to learn & except all the help one will give. I sure would like to speak to the person doing the video, if he would not mind answering some questions on some, along with some guidance on the subject as well. Thanks Gregg

[@lorensimons924]

A great video! I found myself taking lots of notes, especially on what oils to use where. It would be great if you could do an introduction to oiling video, talking about characteristics and uses of your favorite oils.

[@Tonyv1951]

Terrific video with very clear, articulate explanation. Thank you for making it. Fascinating from start to finish.

[@pravinkansara965]

I would like to say this is a fantastic video well photographed and narrated, i am a hobbyist and love repairing old watches and this a video which inspires me a lot please keep up with it so that people like me get the most and enjoying repairing thanks a lot will be watching the videos thanks

[@lingnaikee]

Thanks for posting these wonderful clips! i found them so inspiring for me even though i'm not a watch repairer, your patience and enthusiasm for your profession are what i need for mine.:)

[@anthonyedgar3674]

I am absolutely amazed at how a watch works and wont to learn more so soon i will do your course and thanks for sharing your knowledge with us Mark

[@jmfa57]

Thanks for an amazing, outstandingly well photographed and narrated video! This 3 part series is amazingly educational for neophyte watch collectors such as myself. I look forward to more of your work on KZbin!

[@WatchRepairChannel]

Thanks for the feedback :)

[@ctnnpt]

Great work! Could watch your precision craftsmanship all day!

[@WatchRepairChannel]

Thank you

[@jacquesmoens4109]

Hello, I thank you for a so clearly description and illustrations, go forward I support you.

[@buzzhack4778]

Mark, thanks for inspirational, informative and enjoyable videos, you are natural teacher. Keep on keeping on.

[@terregarob]

What an excellent video. Simple clear instructions and high quality images.

[@daviddahlgren347]

Hi Mark I always enjoy your videos. I was wondering if you could do a separate video on how a calendar works. I imagine they all have pretty much the same mechanics. Thank you Dave

[@mcstyle24]

fantastic video As you said that top and bottom pivot on the pallet fork should not be oiled. why? Would that cause the watch run faster which cause inaccurate time?

[@chuckgentry3613]

Beautifully presented and explained as always Mark. Thank you for sharing!

[@WatchRepairChannel]

Thanks Chuck

[@georuiz74]

Brilliant - thank you Mark. This helped me solve an issue with an old Caravelle which I could not get the date jumper to work on. Now works perfectly - thanks again :)

[@anyoneforapint]

The third and final part was well worth the wait. Excellent videos.

[@WatchRepairChannel]

Thank you - that's kind of you to say.

[@wdc916]

First I commend and thank you! You are an outstanding instructor. I find all of your video’s captivating and so helpful. Question: at 16:39 you state, “the top and bottom of the pivots of the pallets should not be oiled at all” Why? this being a perpetually moving part.

[@markh.harris9271]

Beauty , dude; really appreciate you making these videos. I am hoping to get into this hobby. ... have learned so much from you. Thanks. marcus

[@charleshunt3806]

Hey, not sure if you could do it but I just purchased a Time Men's Expedition North Titanium Automatic 41mm Watch And I was curious if you could possibly do a video on the maintenance of that one your videos are so detailed and so great I would like to be able to do it myself if possible and your videos are so good. I think I might be able to if you did a video on it and if not, it would give me a really good understanding of what’s going on in there . Thank you for all that you do.

[@Martyn0001]

You are very skilled. Thanks for sharing this. Incredible.

[@LeonJakub]

First watch movement I failed, miserably! Shame, it was an interesting one, but I had underestimated it's complexity. Thank you for the video, I will come back to one of these movements at a later date!

[@vanlifenomad]

Superb Mark, thank you for helping my vintage watch business as many times I use your info to correct a watch

[@rayscrafield2106]

Thank you so much for a very well done, informative video. I've always wondered about watch repair so now I have some idea of what is involved. What brought me here today is I have a Timex Expedition day/date that keeps perfect time but all of a sudden the day/date function has stopped working and it drives me nuts not knowing what day it is. I can set both day and date but it never changes from day to day. Can you possibly give me any suggestion as to what I need to do? The watch is not valuable enough to pay much for repair so if it's something I might do myself, I might give it try. Thanks again for your efforts to show us how it's done.

[@esric50]

Thanks for sharing your expertise and allowing us to look over your shoulder

[@douro20]

I've watched an instructor at the Lilitz Technicum reassembling a 6497 movement, and he likes to spread out a good portion of grease on his mirror-top work table and use that to lubricate the setting wheel clutch. Apparently ultrasonic machines won't damage the balance pivots, so in the video he goes ahead and removes the cap stones on the balance wheel.

[@paulwilson3434]

Mark. Thank you so much. You are really an excellent teacher 👨‍🏫! ❤️

[@gerrymaurice8484]

I have always been fascinated how a watch works. your video shows it very well keep up the good work. Gerry

[@WatchRepairChannel]

Thanks Gerry :)

[@24hourgmtchannel64]

16:30 prior to the introduction of 941/9415, 9010 was used on the pallet stones. My charts show 9415 for 28,800 and higher beat movements and 941 for sub 2,8800.

[@Rob_W]

Pity about the missing footage. How about a clip dedicated to oiling a basic movement? You do good macro shots and it would be nice seeing exactly what to oil with what type of oil/grease.

[@WatchRepairChannel]

Thanks for the suggestion. And thanks for watching

[@anderseriksson4812]

Thank you once again for another splendid video! :) Sad that the camera shut off during the assembly and oiling of the keyless work. Just a little question; What is the reason that you are not oiling the pallet fork pivots?

[@WatchRepairChannel]

Yes - I was quite upset when putting the vid together, it seems that there is a 15 minute limit to the recording function on my camera. Now I know :) You do not oil the pallet pivots as it is generally accepted that the liquid friction created by the oil is more significant than the dry pivot in the jewel jewel hole.

[@malix74]

You would have been a top surgeon. hats off

[@somegoddamnguy]

Excellent series, thanks for all the information! You mentioned regulating, will you do a video about that?

[@WatchRepairChannel]

Thank you - I will be getting on to timing and regulating soon.

[@cameronkimjones]

Thanks for this. I found it hugely useful in serving a similar AS movement.

[@yuriyvakulenko]

Mark, It is fantastic! Watched your videos many times. Very useful tutorials. I'm beginner watchmaking enthusiast. Very helpful in my first steps. Do you have any plans to release some versions of your videos for very beginners? How to service a watch with minimum amount of those expensive machinery and tools? I'm investing in my tools step by step. But it is painful to have all those hardware from the start. It would be good to have "lighter" version of videos about servicing spring barrels, friction pinions, washing parts etc. Thanks again. And keep it up! Yuriy

[@JoeDplummer_]

You make it look so easy! Thank you!

[@slkywavs4287]

This is the best video I have seen on the Internet. Thank you so much for sharing. I feel I learned more from this then any other series I have watch and will probably be viewing it numerous times as I will be working on the exact same watch. (My first attempt to fully take apart a watch). Can you tell me what type and brand screwdriver you use? I am finding the ones I have are just not doing the job expected and need to keep replacing and hoping to find the right ones. Also, someone asked what the green stuff is called that you use for cleaning. Did you say it's a gum? Once again I would like to share my appreciation for your video.

[@jd1838]

hello friend thanks for sharing this video, I have a question for you why on the first try the steering wheel didn't work? thank you

[@Isahiyella]

Amazing lesson! You are a great instructor, and just watching this video is truly inspiring. Can someone recommend a good beginner toolkit that would include the tools used in this video series? I have purchased a few old non working watches, and would love to start working on them. Thank you for these videos, truly mesmerizing to see a craftsman at work.

[@SK-2175]

Dear Mark, my rotary watch with movement 2061 had problem with the calendar forwarding. The quick set was OK. I will need to remove the movement from the watch case but it seemed stuck . Your video did not show how was the movement removed from watch case. I removed the crystal top and try to push the movement out from the top, but no success . Looking forward to your advice.

[@longboredterrie]

You are a very good Teacher, Thank You

[@gwsjr1]

You mention some people use lighter fluid to clean the balance. This being a petroleum based product means that it would leave a residue on the parts it was used to clean. Should the parts be dipped in alcohol or other solution to remove the res from the lighter fluid?

[@garrybatt7139]

Thank you! You make it look so easy, you have inspired me to learn more.

[@arke7713]

Hey thank you for theses wonderful videos. You said something wrong about the pallets oiling. You have to use the Moebius 941 for 3hz movements and the Moebius 9415 for 4hz (or more) and not the opposite as you said.

[@WatchRepairChannel]

***** this has already been discussed further down in the comments :)

[@geoffreylotz3661]

Ah! I was hoping to see it on the Timegrapher, just to check lift angle and approximate amplitude. I have an ASST 1950/1951 on the bench - a learning/practice job - and I get it to about +2 s/d , 0,2ms beat error, and about 220 degrees amplitude but I am not sure if I have the correct lift angle entered (53degrees). I had a problem with it going completely haywire ( very fast) in dial up position, and re-watched this series. I think I had incorrectly inserted the pivot past the little spring on the....minute wheel??..( this one is a little different to the movement in the video, but not much) .....and also hadn't correctly seated the cannon pinion. In dial up it's now much better (around -8s/d) but I was just looking for the lift angle confirmation....I'm learning so much. Thanks for the videos, Mark.

[@WillFlyGuitar]

Another superb video - well shot and well produced, and with immaculate workmanship. My "Swiss Emperor" is in good hands! :-)

[@WatchRepairChannel]

Thanks Will :)

[@kennethschapira9571]

This was a great series, so informative. Thank you for making these.

[@WatchRepairChannel]

You are welcome Kenneth

[@walther9161]

Is there a video anywhere n how to tighten the friction pinion on that wheel? Desperate for a “dead hands” solution.

[@geoffreygreenhalgh5961]

Wonderful, When will that watch need the same treatment?

[@gordbaker896]

Extremely interesting. It seemed the shaft of the wheel in the bearing ( the smallest of the 3) under the head wheel was loose in the bearing. Perhaps it was the lighting.

[@richardmcginnis5344]

this is awesome, i want to fix watches. i noticed when he is putting the calander back on the crown looks threaded on to the stem crooked, is that something that is gonna destroy the stem or crown eventually?

[@larryrichards3668]

Thank you very much for the very clear and informant video lessons.

[@ronnylenaers4531]

Mark, are you sure to use 941 for fast ticking watches instead àf 9415. I waq told the opposite.

[@Canon060009]

Fanstatic video, thank you so much! I am wondering what kind of oil for escape wheel, the first wheel, third wheel? I'm not good at English, so I can't hear you clearly!

[@davidbrassfield2855]

By what guidelines do you usually use to decide which oil or grease you should use? Very well put together video by the way. It must grow irritating to get the camera to focus on all the micro objects that you are showing.

[@theosmit5506]

Very inspiring video, can you tel me wich oiler you use for the different parts in the watch. Thanks for the video's

[@derekwilkinson7939]

Three very interesting and useful videos. 👍

[@derektalbot4887]

Is there a reason for using metal tweezers at all or could you get away with a brass set for everything?

[@wohltemper]

Hello Mark, great video as usual, I am so glad I watched this one because I have just completed my first servicing of a wristwatch, a Timex100 with an AS 1940/41. It was displaying classic 'loose cannon pinion' symptoms, and still is after servicing, even though I tightened the cannon pinion. But from what you say the friction device is on the third wheel, not the central wheel as usual. The watch is running nicely but the hour and minute hands start to slip after about 15 minutes, especially around the date change. What do I need to look for and do to resolve this? Many thanks and keep up the great work./Colin

[@mariansinoaie2303]

Hei man, I know this is an old video but here's hoping. Is there any way of repairing a stripped crown weel hole I did not know it was a left hand thread and I stripped it... Any answer helps. Thank you!

[@robertproctor198]

Great 3 video's & superb clarity thank you

[@auburnsenn2040]

Hi there and seeK your advice. I am stuck with AS 5008 on FORTIS ALARM WATCH and need parts that are short in it.. Are there any models out there that will match The said AS 5008??????

[@AndrewMellanby]

Super video! ... Do you ever clean the calendar rings or dials ? Just that I noticed some discolouring around the 14-17 of the calendar ring on the video.

[@onlyvintagewatches]

I am resurrecting this video comment section, since I am servicing an AS 1710/11 movement. Can you tell me how I remove the cap jewels on the train wheel bridge? Got some filament stuck inside

[@ignatiusandi2802]

I have almost the same movement vintage watch from my grandparent gave me.. the minutes Hand is not working properly, maybe take 10-15minutes in real time for 1minutes on the watch. However, the second hand is running fine, I did match it with stop watch, it might late 1-2second but I think I can live with it. Any idea what is the problem?

[@dietznutz1]

Can ultrasonic cleaners be used for cleaning the movement?

[@gopalakrishnanramaswamy6562]

The name of the solution you are dipping the balance complete & the jewel?

[@ianmedium]

Excellent Mark, great work. Have you ever heard of an old Swiss make called Election? I have just purchased a beautiful watch made by them I am guessing in the thirties from the style, the movement has 3 adjustments and 15 jewels. I just liked the look but am not familiar with the name and wondered if you are.

[@WatchRepairChannel]

Not seen one but just had a quick look in Google - Nice find :)

[@hermogenesgutierrez767]

Hi, can you show us here about the AS 1700 movement. Having problem with the calendar function. Thanks in advance.

[@ericscamman1685]

Of course you were able to get the train wheels in all the jewel holes on the first shot haha great videos!

[@opal177]

Thank you so much. It is funny how one tends to keep quiet, hold breath and hold the tong straight while watching. XD

[@TommyTightPants0115]

Hi mark fantastic work i could watch your videos all day. Please will you make a video on regulating the watch IE timing / beat and also if and when please could you make one on a cannon pinion explaining what the cannon pinion does / tightening methods ps happy new year best regards ady

[@WatchRepairChannel]

Thank you - I will be getting on to timing and regulating soon. Nice suggestion regarding the cannon pinion. I will keep this in mind. Happy new year to you Ady.

[@stephenwheeler9286]

Superb! Learnt so much. Only found your videos today, have been looking for months. Did you only oil the exit pallet stone? Have you considered doing tuition courses? Cheers Steve

[@davidclark5138]

Great video series mark. I lack the very fine dexterity to do this watch service work. Can I send you my pocket watch for service, was running fine but I got off my maintainanc winding over the summer and went to rewind, , ok,.but has not restarted. Can I send you my watch if possible.?

[@dreja123]

In the video (15:56 on) you are saying, that you are using Moebious 9415, while for 28800 you would use Moebious 941 .. Is this information correct ? Can 9415 be used for both low and high speeds ( BPH ) ? Thanks

[@testpiloterb1828]

How many different oils and greases are needed to be sufficient in having enough oil or grease to repair watch movement?

[@glynnbooth2453]

Could you tell me where I can get a as1900 movement please so that I can service one whilst watching your video.

[@frat7939]

Thanks to increase our passion!

[@DaKarst]

What if the train wheel bridge completely covers the wheels and provides no room to adjust some of them with a tool? Working on an AS ST 1802 movement but can't seem to get the wheels spinning freely

[@galtbarber2640]

"replace" in America is usually taken to mean using a new part rather than meaning "put in place".

[@rjavocado]

You're not supposed to oil the pallet pivots? Please explain!

[@WatchRepairChannel]

It is not recommended to oil pallet pivots as the oil will create too much drag and impede the movement of the pallets as they move from banking to banking. Although some watch repairers may use a very low viscosity oil, I am of the opinion that it can cause more problems than it would solve. It is the same with the minute recording wheel on a chronograph - oiling the pivots will potentially impede the movement of the wheel rather than help it.

[@palmergaz]

Thanks for these videos they're marvellous! I am just beginning to teach myself watch repairing. I have a small amount of tools albeit crappy eBay kit. How much would you recommend spending on tools as a beginner- for decent stuff, and do you have any links for suppliers of tools and such things as oil and grease? Cheers

[@PozaDomem]

Greatest video I've seen ever...

[@jasonrobb9814]

Hi all i have an A.S 1880/81 very similar has an issue though second hand moves fine showes beat error and rate amplitude ect but the hour and minute hands do not move any advice would be great

[@20MaRk23]

How much would you typically charge for this service.

[@nateblubaugh729]

I think this would make a good TV show actually, it would be nice to have watchmaking on screen.

[@fatcat2939]

Is it a workable idea to refinish a SS bridge that has a bad surface finish (random tool marks). Movement is in a display case.

[@otispotis47]

Do you know the size of the A Schild 1901 mainspring?
