How did you know I'm watching this in my pajamas with a cat in my lap?

[@danieljimenez5887]

My cats help by clearing my bench of all pegwood! 😂

[@TweezerWieldingLunatic]

Eventually they become the parts stash. 🫣

[@VWatchie]

😂

[@richardross1164]

This was highly educational and entertaining too. For a fumbling amateur like me, your valuable tips and enthusiasm for the craft are really motivating . Thanks so much!

[@adfpv1153]

It’s the little things Kalle, but soooooo useful. Thanks for all you do dude👍😁

[@pammoore8963]

I'm a big fan and I've watched this video three times! Makes so much sense! Thank you!! Pam from Hollywood, CA.

[@BrianMCarroll]

I’ve developed a relationship with my watchmakers over more than a decade. This video makes me appreciate them even more. Thanks.

[@richardkent2200]

Once again genius-this stuff of yours is simply beautiful-I just love your presentations

[@tomholloway7566]

Wow! I have never heard anyone explain much about screws, either in courses or textbooks. Thank you Kalle.

[@monte4150]

Thanks Kalle!

[@r.o.1330]

.....still laughing at, "in the back bedroom, in pajamas with a cat in his lap!"

[@richardburns4708]

Thanks Kalle very educational and worthwhile video for the extreme beginners like me.

[@Aco747lyte]

Your knowledge is awesome! I really enjoyed watching and listening. ❤

[@TheTomIves]

Thanks. Have lost a screw. Now I know what to look for in a replacement

[@mikebruegger8654]

Nice review and mention of a screws use. They are themselves for a reason!

[@alterhype]

This was an awesome post. I’m new to hobby and working on Seiko 7002 movement. Screws are important! No room for multi tasking in watch repair.

[@alaindrolet_atlt_2019]

Geez important !! Of course I made some mistakes with screws !! The better is to find the mistakes 😂😂😂 . Thanks Kalle it’s another interesting video, watchmaking is always about details ! So always stay focus about each parts and screw you put on, that surely make you a better watchmaker ! Best regard dear Kalle ! ✨👌

[@MrMcGuy]

Excellent information sir. Everything has been designed for a purpose. Well done.

[@exious1]

Thank you, I am the guy in his spare bedroom with a cat on my lap. I don't have a school close to me so this video helps a lot.

[@davidcrandall4958]

This information is priceless as usual!

[@walther9161]

That’s funny. I keep the screws with the respective part…did exactly what you showed!!

[@brittcave8447]

Another excellent video, Thank you.

[@icemantree]

very interesting and entertaining, you did a great job explaining... for a DIY watchmaker as myself... a huge help!

[@Al-po2oh]

Very helpful, maybe next time show the screws going into the respective locations on the movement. Thank you

[@devonshire56]

As one Dutchman to another dank-ye-well. This is a good reminder to pay attention to detail. I sometimes have more than one watch on my table and keeping everything organized is important because mixing screws is a sure way to watch damnation.

[@okclm]

Thank you for the guidance and information. Very educational and appreciated.

[@WristwatchMedic1953]

I have never heard anyone ever explain about watch screws. A great video. Thanks for the video.

[@michaelwoods8456]

The classic example is the three screws on the barrel bridge in pocket watches, one of which is sometimes shorter than the others because of the setting mechanism on the dial side

[@RomanSchatzphoto]

Excellent information as always. Thank you.

[@watchrepairwithchris4346]

I can check what I did again. thank you.

[@nathanhays1746]

Love it!

[@MexicoBeachFloridaLiving]

Kalle, I've used my cat(always in my lap) fur to shim a cannon or hour hand on a few occasions. It works great!

[@celinecicoria84]

You are the best.. you explain everything’s so good .. many thanks for your pills

[@IgorGjurovski]

I am the guy in pajamas, but without cat! 😂

[@user-gm8fc9dk4j]

A beautiful presentation. The "random selection" was a great way to point at the depth of the technology and the problems it needs to solve.

[@onenessapproach]

I am just getting started in my late 50's. I appreciate this video as it knowledge that is not readily available to me. I am looking at low level restoration of pocket watches and cleaning up and polishing newer beat-up watches. I am an amateur silversmith and want to use that knowledge to make watches look like and hopefully run almost like new.

[@aidanbyrne5561]

Thank You. Very interesting.

[@kennethcargill3512]

Thank you for the detail. Im hoping to get into hobby level watch making and this is exactly the kind of information that Im looking for!!

[@terriannrogoski5978]

I have enjoyed watching your informative videos.

[@erikblicherstasiak2803]

Wery informative Kalle. You are soo evil to your students with those extra stews 😂😅😉

[@zerolatitude2923]

great show thank you!

[@user-mc8zv1kq1l]

Very interesting!

[@ElderPinto254]

bedankt Kalle erg goede info .... i had net een uur gezocht naar een verloren schroef en gevonden dus dacht ter onspanning even Kalle kijken en wat is het topic lol hahaha ik weet wel waar ik vanacht over droom schroeven!!

[@amandagelien9612]

Kalle a GREAT VIDEO-I have done it too many times- been there done that got the teeshirt !!!!

[@Rauz11]

Great video 🎉🎉

[@vlad4281]

Thanks Kalle, another brilliant video - this has been the missing piece of the assembly jigsaw puzzle for me - I realise I have been flying somewhat blind up until now - As always I'm so grateful for your kindness in sharing with us your wonderful experience and knowledge 🙏

[@mellamoisaiah]

This was so helpful!

[@johnrieley1404]

excellent, thanks, very interesting to me; all makes sense, not just diameter, length, but shape of end, shoulder, etc. Somewhat the same in macro-mechanics with its different types of bolts and nuts.

[@KillingTimeWithNorman]

This was an amazing video! Soo informative! 🍸🍸

[@andyhansen3117]

Thanks Kalle, I always thought there was a logic to the screws and you explained it very well! I just don`t know how you are able to put extra screws on my bench when you live so far away!!

[@equaliser2265]

Wow,Sir a Master class I appreciate your time and knowledge.

[@nuevohermes]

Thank you

[@stevegall7438]

This was interesting but what would be useful are tip on how to sort screws after cleaning a movement. How do you sort the screw into their correct positions

[@alainbovier5734]

Salut collègue, je suis horloger, j’habite à la Chaux de Fonds en suisse et tu as tellement raison sur ce point, une bonne boîte d’assortiment de vis sauve la partie 😂😂

[@frankjames4573]

Great Vid Calle... The screws with what you called a tapered shoulder, are called "COUNTERSUNK" screws... Just to let you know ... As for my watch case... £$^$&&* piece of wasted time ... I completely &^%£$! it up... I was so £"$^%&* pissed off... Then I thought ^$%£ this watch making hobby... Once I calmed down over a brandy coffee. I thought oh well... Start over again... lol Frank...

[@johnadams8212]

Great tips. Thank you!

[@alaindrolet_atlt_2019]

Dear Kale ! I will begin to wish you a Merry Christmas, sorry I’m one day after ! Hope you got a great one with family and friends !! I write my Christmas wishes on this video because, I clean watch part and this time each screw will going at the right place for sure, after seeing your video, I recognize each screw and his fonction. So just thank you to show us those so important details !! Best regards!! 🎄

[@markbyrum4743]

Good vid. I learned a lot! Thanks. Keep at it!

[@dunderhay9169]

Very helpful, thank you 👍

[@tomg6117]

I don't know why you thought we wouldn't find that subject interesting! I thought it was great! Thanks Kalle!

[@robertmabry4172]

Great information

[@Tinman97301]

The cat comment hit hard 😊

[@OttawaInHD]

Great video

[@watchwhisper]

nice video i always learn

[@nciraldo]

This is excellent for all the reasons that have been mentioned, but also: when you lose a screw, this can help you have a better idea by looking at the movement what kind of screw you need! Also, I just wanted to say that these videos are extremely helpful when watchmakers are too busy to provide education and watchmaking schools are a few and far between where I live.

[@markrung8051]

I love your videos

[@Tiocacike]

Im the guy in pijama with a cat in the knees working on a watch 😂 You are a perverse mind with those extra screws XD

[@frankie984]

Thank you ,you just gave me light years of watchmaking

[@user-hc1xd8wu8p]

WOW, it was a slow day at work today......................

[@phillipreifman2272]

Just letting you know that everything you tell us is Highly Intelligent and nothing is taken for granted. I appreciate every piece of advice and always learn more from your videos no matter how trivial it may seem. You are an excellent teacher and do an excellent job of breaking down the science and theory. Thank you for what you do!

[@magicofwheels]

super informative😊

[@mjonathan100]

What a gem this guy is for people like me who are learning watchmaking at home after a fatal medical condition and cant afford to go to watch school. Excellent sir keep these coming

[@rossjackson3670]

Kalle. Thank you. I knew about screws. Honest! Now I know why I knew about screws. Taking your time to help us lesser mortals in the learning of this hobby is an excellent thing to do. Take care. Wish you well

[@user-sd6il7ut3o]

Top video, bedankt voor de tips. Al doende leert men😇

[@Looey]

This vid was EXCELLENT ! Nowhere else have I seen watch screws explained like this !

[@WardiTime]

As usual Kalle - detailed, serious and informative, never screwing around! Thank you.

[@htchtc203]

That was good introduction of screws. And also some general idea of watchmaking. Thanks Kalle.

[@Mr26Huffy]

LOL! That's me working on my mods in the spare bedroom with not too infrequently a cat in my lap or trying to knock a project off the bench! Too funny my friend!

[@szbalogh]

In an HMT manaul wind movement one screw is right above the winding stem. If you put the longer one in from the barrel side you can assemble the keyless works but can not switch to the time setting position. Took some time to figure out whats the problem.

[@ron2143]

As an amateur with only a few years 'experience' under my belt, I always find your videos not only super-informative as an important source of 'real' knowledge - but extremely easy and enjoyable to watch. Never boring, far from it. This one really helped in many ways. Many thanks Kalle.

[@paulpadilla6913]

Thanks Kalle! Being fairly mechanically inclined, a former auto mechanic among other jobs, I am familiar with different types of screws and their uses. But being a self taught amateur I had to learn to apply my prior knowledge to watch repair. I have still been guilty of using the wrong screw but usually not the wrong type but the wrong length. Fortunately I did not cause any damage and I have learned to pay more attention to the screws, especially screws of the same type but different lengths.

[@spacelord1913]

I had a longines pocket watch from the early 1900s, it stopped and I found the screw that secures the movement in the case had come out, it has about 1/3 of the head missing, almost like a semi circle but a bit bigger. When tight, the semi circle secures the movement over the case edge, stopping it from sinking in too deep. Not sure why it has a semi circle shape, it might be so you can half turn it and allow the movement to sink deep and ultimately pop out the front of a case, but not sure, it seems redundant in my watch. I find these movement retaining screws come loose often in old watches, so I used loctite to secure it.

[@markrung8051]

I started out in my bedroom, then qualified professionally 15 years ago. Your words are so true.

[@sfann1ng]

Thank you for passing on such wisdom! I would hate to screw over a movement for getting it wrong. 😊

[@hanslindgren7175]

Thank you Kalle! I love when you put 3-4 screews on The bench for the überstudent.😅

[@khronosbest9448]

it is always easy as long as someone explains it to me🤓 Thank you Kalle !

[@gmotionedc5412]

Love it🎉🎉

[@paintsteelblack]

Thanks this was interesting 100% as all of your videos just wanted to give som positive feedback 👍 hello from sweden

[@1999zrx1100]

The thing I notice with some watch maker videos is some are using metal tweezers that look like they could be leaving fine scratches on the various parts. I never notice that on your videos. Maybe I’m too critical of such details. 🤔

[@diaga67]

I have not disassembled my first movement because I am afraid of mixing up the screws, forgetting where they go, etc. This video is incredibly helpful for me as a complete beginner. Thank you!

[@neil4701]

Believe it or not, that was absolutely fascinating and highly entertaining!

[@williamevans9426]

I've only just discovered your channel and find them informative and easy for a layperson like me to understand, while also being relaxing! Best wishes from Oxford.

[@thefosterfam]

Very educational and provides much better understanding of the screws holding things together, thanks very much!

[@Craig_79]

This is my favourite channel right now 👍🏻 I agree with you. The most common one that springs to mind, Omega 1120 with a perfectly cut circle on the barrel cap and a domed not polished screw on the barrel bridge. Note all screws came from the 1120 😀

[@MrRoundel]

Thanks, Kalle. More useful info. I think I must pull that sneaky extra screw trick on myself sometimes. ;-) Cheers.

[@matthewpritchett8760]

As a mechanic, I have a whole drawer of nuts and bolts. I never toss them, unless they're truly broken.

[@clive.r1414]

A really good video Kalle! Basics are the important things to make any task easier. Merely playing at watch bashing, but I learnt early on the importance of keeping the screws in some type of order. Your explanation was priceless, thank you.

[@jeffmuller9020]

Ive watched several of your excellent videos and I was always overwhelmed by the screws. Thank you. A video suggestion would be taking apart a movement and showing the screws on disassembly and then re assembly. That would be extremely helpful.

[@johnhinkey5336]

Well, that's just screwy! 😁 It actually was worth the watch (pun intended)!

[@zackackerman3180]

Thank you Kalle for your insights and knowledge. I am always learning and this is a prime example of something I do and not pay close attention to. Well I will now be studying screws a bit more closely. Cheers

[@garymclay9885]

My whole life I’ve always loved mechanical watches and thought they were above my simple understanding. Then I found this channel. How interesting and a great way of explaining things that makes sense of it all. I’ve just retired and looking for an inside hobby for the winter. My eyes are not what they were though. Great job my friend. 👍

[@tmmkk1]

Kalle, this was very helpful. Thank you
