Hello just got done watching your video, and just has to let you know, Don't be too worried about your videos not going as you hope, it is nice to see that things don't always go as planned and aren't perfect, And the little hand you fabricated I think was great, a very nice size, If I was your customer and you did that for my watch and the time you put in on it I wouldn't complain 1 bit. Nice Job, I enjoyed it a lot. And I enjoy your Channel Keep up the good work Stay Healthy Stay Safe - R.M.

All I could think of as I watched this video was the phrase my Mother often used: "The patience of Job". My spouse is an avid modeler--mostly aircraft--and I've watched her literally stress-sweat over old, discontinued and rare kits. I am way more "macro" in my chosen hobbies of quilting and jewelry making so it's an abiding mystery as to why such finicky twiddling gives you all such joy! Yet, still, when I want to relax and feel good about things, watching watch repair and restoration is really satisfying. I could watch other people doing it for days ; ) Thanks for the opportunity to entertained by another persons frustration and tenacity--better you than me!

[@tonycollard4185]

Hello Mike, Anybody that works on watches will have had similar experiences of a watch's problem escalate during the repair/service process. Credit to you that you made it to the other side with a running watch and credit to you that you kept it on film to show all of us. Not many would. These extras are what adds to our experience to make the next repair better and smoother! Keep up the good work!!.

[@greendomeno6]

I'm not a grave robber Mike but there's a thought.. Fabulous work mate and definitely not a failure if its running. I promise the next one will be a doddle!

Also got a Citizen radio controlled titanium eco-drive the seller said was dead and yes it was but following Citizen's advice of putting it for a night under a bright light source... it sprang into life and its like a new watch. Tomorrow I am putting a new lithium cell upgrade into the Antonio (that sounds a bit weird...) to replace the weak capacitor cell it has, the watch is amazing being a see thru baby blue acrylic and the dial is skeletonised as well as the bottom case section has an exhibition caseback to show off the rotor. Glad to see you are out and about on the videos again.

[@Michel-7.7.7]

33:33 a couple days ago, i had exactly the same problem for more than 2 hours. Then the spring went flying and i went crawling with a magnet, couldn't find it. Now i have a gorgeous Fama, 25 jewels, not working automatic, calender watch, with a damned rare caliber, without clickspring.

[@MyRetroWatches]

[@alanmckinnon6791]

Well Mike, at least you got the bloody thing running eventually!

[@avianfish8732]

Spring setting is due to Hooks Law. Metal looses its flex after it is repeatedly activated over time because the act of stressing the metal causes its crystaline structure to change. When a spring is under tension in a barrel even the changes in temperature from day to day will eventually cause this, but mostly it is everyday use. Often springs on broken watches sit 'overwound too' which doesnt help. Set springs are on the way to break but not necessarily quickly.

[@davelowey3074]

Great video Mike, what an oil filled mess, brought back to working order it's definitely not a loss, thanks lad, i myself just fixed and seviced a Raketa 2609 ha in a Seconda 36mm gold plated case, i was impressed with the 2nd wheel which the cannon pinion goes on, it was jeweld for the seconds i like that alot, not seen on others eta or Seiko, impressive, enjoyed you video cheers Mike, glad you and your family are ok mate, thank you. 👍 P.S i have a dedicated pair of tweezers extremely sharp just for hair springs, they are challenging for sure.

[@mickeyx6746]

Stout fellow! You bore that well, and I admire you for revealing your adversities as well as your triumphs. I do believe that because of the fixed lugs and the dial face that the watch may be from the 1920s or perhaps the early 1930s so I think it’s even older than you guess. Also, it was probably also an economy type watch to begin with, so you are not really working with a watch that had a descent build quality and that would make it all the more difficult to restore 90 to 100 years later. Again I’m not an expert but just offering my insights for your consideration. Thank you! I’ve enjoyed your video! I have bought you 3 beers as per the above link! Cheers Mate!

[@MyRetroWatches]

Hi Micky, firstly thank you very much for your donation I really appreciate that immensely. You might be right about the age of this watch as I do have a feeling its older but I could not really find info on the movement which I normally can online. If you get a date for the movement it gives you an idea of the watch. The thing with Marvin is that they appear to have made their own movements and as such seem to be quite collectable from what I can gather. Thank you so much for watching. cheers!

[@tommiller1315]

Well Mike, I got a bag of watches for about a tenner. Just one looked interesting but a non runner, the winder had been replaced with what I discern as from a Fossil watch. Nothing to lose, I did the oil trick and a wash with IPO and dry. Oil is a very thin one, not 3in1. You did have me laughing with all the oil in yours by the way, looked like it had fallen into an engine! The face looked like it had been wire brushed which had sadly removed the plating but apart from that, it cleaned up and now runs within a minute a day. Hunting on Google, I discover it is a 1932 watch, Swiss made 15 jewels, small ladies, imported to New York and the jewellers name "Newsol" engraved on the main plate. Only thing I am uncertain of is whether the 14K inside the back is a model number, or indicates the white metal is 14K gold. As you can tell, I enjoy my experiments but am not a repairer in the true sense. I do have a quartz watch filled with baby oil, and running well for some months! Thank you for your KZbin channel which inspires me to go on and maybe attempt a strip down one day.

Hello Mike. Mike d. Here stateside. My tip for hairspring d is this. I have had luck simply while the hairspring is on the balance turn the balance upside down holding down the bridge grab the balance wheel with tweezers keeping the balance wheel straight up lift the balance until 3 quarters of the coils are seperate move the balance wheel north about 5 to 10 mm then south then east then west. I have found many times this will help remove any natural defects in the spring from wear while working in the watch. But first I clean the spring as you did. Blessings to all. Oh Mike that collet would be moved to the left to out that dot at 3 o clock. Twist the fine screwdriver to your right just 1 mm. Mike d Stateside.

[@MyRetroWatches]

Interesting tip i may try this next time, thanks

[@michaeldevito5575]

@@MyRetroWatches Hello Mike. Mike d here. Stateside. I just adjusted the beat on my 40 Ingersoll watch and it did no good on getting a reading on my time o grapher. Here's how I adjusted the best on my 40s Ingersoll. Remove the balance from the watch. Lay the balance on the table a pad or what ever you have. With the balance cock down and the balance wheel and hairspring up look at the dot on the spoke of the balance wheel this dot should be absolutely 3 o click and when installed in the watch it will be 9bo clock and nearly perfect line with the pallet fork. Most of the time you'll see this dot at 2 9 clock I find the watch still ticks nice and keeps time pretty good. 8f you do want this for at the 3 o clock simply turn the balance upside down. Oh. This dot is right wear the line up jewel is the jewel 8s on the upside of the balance assembly With the balance bridge or cock up and the hairspring and balance wheel down gently pull the balance wheel toward you you'll see the coils sperate enough to get a fine blade screwdriver into the notch on the collet. Remember if the jewel needs to turned to the left the collet must be turned to the right and visa versa. For this adjustment place a fine too screwdriver into the slit and turn the Collette to the right just bout 1 mm. Now pick up the entire balance so the hairspring steps in it's new spot. Then check that dot and it should be at 3 o clock. If not turn the Collette the other direction jusT 1 MM. Hooe this helps Mike. Blessings. From Stateside.

New for new, I wonder how accurate a watch from the 30s would be compared to a later watch from the 70s. While craftmanship was much higher in the early century, tooling was much improved in the last decades - much more precision tooling and accuracy. If you could compare a new luxury watch from the 30s-40s with a new luxury watch from the 70s-80s, which one would be more accurate ?

[@kaiamos3195]

Great entertaining video as always. I feel your pain. Try a ORIS 471, Very similar to your Marvin. Its being on the headache shelf of my bench from the beginning of my adventures in watchmaking. The original was as full of oil, as yours, I can get the arm flicking smoothly between the posts, have a new mainspring and two balance cocks and springs with wheels. Can i get it ticking,,,,,,NO. I just cant see in it to line it up all up. When i feel particularly sadistic I have another go. I will get it going but look at it like this: A VW polo will wear out before a VW passat or combi van because everything is smaller. If the wheel is smaller it still needs to go around either the same or more times to go the same distance. The metal is the same. The bearings are also smaller so will wear more. I am no expert but damn these things hurt my eyes. :)

[@AaronS11979]

With all other factors ignored, a watch that runs too slow that has the regulator pinned far to the (+) means the hairspring is too long. I watched a fantastic representation of this by some youtube teacher (can't remember which) who held a vertical pendulum. As it swung, the distance it swung left to right (amplitude) didn't change the time it took to swing. But shortening the string (or lengthening it) changed it dramatically. The shorter the string, the faster it ran. The longer the string, the slower it ran. This in essence is what the regulator does. It shortens or lengthens the "string", or hairspring. So if your regulator is pegged, and you know everything else is right, I'd have to assume the overall hairspring is too long. Maybe you were sent the wrong one?

[@watchmedraw4340]

I think it's awesome. I have an idea. Maybe the oil on a few of the pivots became laminated. You never know how long ago the oil was put in the watch and the oil mixed with the dirt to almost make it like malasis in February. We all know I'm no expert here at all but it's a thought.

[@MyRetroWatches]

The second service seemed to help considerably so I’m guessing 80 years of use meant a good clean was needed. Has been serviced quite a few times in its life which is good to see.

Thanks Mike for such an educational and funny (oily) video!. I have a small army of radioactive old watches and what do you think, is safe to use it? is safe to work on it, restoring it?

Your advice is to keep them or discard them? Thanks and a hug from Saudi Arabia!!!

[@dodgydruid]

Looking at the timegrapher 52 mins in, the balance wheel seems very much more in harmony with that nice close tracking so thats a plus. Thing is, in the 30's what you have there is just about what you got back then, super precision didn't really come in until WW2 where great advances in engineering and machining allowed watches with amazing precision, my 1947 Avia is the most accurate of all my mechanicals, puts the Seiko's and others to absolute shame how good it is. Saying that, my recent 7019 acquisition has knocked my Poljot Schturmanskie Gagarin from second spot to third as that is a very good movement in the 7019 but not quite where the '47 is hehe I suspect your other issues are simply pivot and gear wear being a 90 year ish old watch and likely all original I suspect if you refreshed the train, the escapement etc, replace the ankh and def look at the jewel settings on the balance staff you might see a nice improvement but that suggests many hours and finding almost impossible to find parts if they are unique to the works unless you can make new ones on a microlathe. Def have a look at the jewels themselves as I thought a couple looked a bit enlarged to my eye but I am no expert and compared to you mate I am like stone age in comparison. One of my subscribers is sending me from America a USB stick stuffed full of Seiko technicians manuals covering just about every Seiko movement going, I am also investing in a 20 diopter large lens on a lamp arm, going to cost a lot but a 20X large lit lens is what I need to do real precision work.

[@christopherjames9214]

Interesting one Mike. I share your disappointment with this one. I'm wondering if you bothered to strip the balance jewels as normal. It's a pity you didn't attempt to shorten the hairspring a smidgeon- fiddly of course but not too difficult if you take your time. I've seen the you undertake much more challenging procedures! Altering the beat error on these old watches is, I know a pain in the bum. I can understand your trepidation if the watch belongs to someone else, but given the condition to start with, there was not much to lose! But we'll done for getting the beast running. Keep up the good work

[@MyRetroWatches]

Thanks. This one was a few years back now and to be honest I can’t remember it unless I watch the video back.

[@dbzamora]

Great video as usual. Bringing a dead watch back to life is always a win inspite of the obvious hurdles and obstacles. With regard to the timegrapher readings, have you tried other lift angles? Thanks again for a very informative and educational video. Stay safe!

[@MyRetroWatches]

Thanks as always Dennis. I found all Marvin that I could find including a 600 which I would think is just a variation of the same calibre to have L/A of 52 hence using it.

[@paradacostamiguel]

I bought 2 watches like this from ebay and I went crazy with them. Full of problems, and none of them work. They drove me insane. The moral of the story is that tank watches are cool to see in instagram, but I don't want to work with them ever again.

[@MyRetroWatches]

Haha. Don’t be put off. I am just to stubborn to be defeated by a watch. I like the look of tank watches but they are small and on my wrist I just did not like the look of this one.

[@michaeldevito5575]

This watch looks like a 39s or 40s. I work on the Ingersoll 40s watches and only get a series of dots for one quarter of the screen on my time o graphed no matter what I do I can't get any reading at all. I some time the watch manually with another watches second hand and it comes out well.

[@martinsmolarik3143]

like for your passion

[@darcybrawataakaontariostac6835]

So thats where all the oil from the EXXON VALDIZ spill went. LOL!!!!!!

[@bfx8185]

This is proper watchmaking , not maintenance. You should go for such challenges. That will move your skills forward. Don't leave it as is go for better performance. I think bottom jewel is cracked.

[@MyRetroWatches]

I don’t mind pushing myself on my own stuff but not others as it ends up costing. The balance wheel screws don’t have slots so guess what… need a special and expensive tool.. typical. Many I see have slots but not this one. Thanks for your comment. Much appreciated.

[@stevewilliams5428]

Did you check the hairspring was being gripped properly by the pins in the regulator?

[@MyRetroWatches]

Yes its what gave me so much trouble one of the pins was bent so I had to re-shape. I really have a lot to learn on hairspring work.

[@menashewalsh5128]

What do you use for first and second rinses?

[@lesliesmart651]

The best way to stop that is to refit the balance wheel then wash

[@AstonColey]

Hi Mike This is a great video and your efforts to get this sucker up and running are marathon. I noticed that the original hairspring has 11 coils and the new one has 13. Can you not shorten the hairspring by one coil which will increase the speed an decrease the amplitude?

[@MyRetroWatches]

This much I dont know. The old spring was most likely from the 30s or 40s. The springs are now made of better material. Also for manual winds they have a "hook" so they can tuck into the barrel so you could not shorten them unless you then remade the hook.

[@AstonColey]

@@MyRetroWatches HI Mike I was referring to shortening the hair spring not the main spring. In your build up you could not increase the speed of the oscillations of the pallet hence shortening the hairspring will make for more oscillations and less amplitude.

[@MyRetroWatches]

@@AstonColey My mistake sorry. I didnt notice this and I must say that despite ordering onliine the replacement for this movement I do not think that I received the right one. A spring could be shortened but its nota job I would take on. I need to master hairpsprings as its my biggest weak point.

[@frazercrump430]

Really enjoy your videos, it is interesting to see the renovation 'warts and all'! Just a thought, did you clean the lower balance cap jewel? I didn't see anything in the video about it.

[@MyRetroWatches]

Thank you. Yes all the jewels were cleaned multiple times plus the watch being through the cleaner twice in the end.

[@vesselingenadiev2526]

Can you please share what is the level of magnification for example in 10:40 minute of the video?

[@paulschaefer5241]

I can't believe someone used that much oil. one good thing about it though you won't have to worry about rust.

[@MyRetroWatches]

Its not unusual to open a watch up to find its full of oil. Owners think spraying WD40 will get it to work again..

[@SergiRuiz_RelojeroTorpe]

Hi Mike. How are you doing with yours? I've seen salads with less oil than that watch.

[@MyRetroWatches]

Hello. All good here. Yes serious over oil. If it was 9010 it would have been $100 worth!

[@boydsargeant7496]

Good try Michael! What movement is it?

[@MyRetroWatches]

Marvin made their own, calibre 610

[@SideWalkAstronomyNetherlands]

Just use a bit of oil if it doesn't want to come out :)

[@dodgydruid]

Gonna grab one of them t shirts when me disability hits the bank this month... oh yes I have done that on me hands and knees lol
