This Chanel is a hidden jewel for Watch enthusiasts who want to know how these engineering works of art really function. Thank you for sharing your knowledge!

I am a well experienced and knowledgeable (retired) engineer and the canon pinion snap fit but yet still allowed rotation.... feature has puzzled me for years. Thank you for the detailed piece of information that has satisfied my brain for today.

As a layperson it never occured to me that the cannon pinion has to function a bit like what Germans call a »Rutschkupplung« (gliding clutch?). Just one more fascinating detail in a virtually neverending list of tiny wonders of engineering and ingenuity. Cheers, Kalle!

This channel is a gold mine.

Fantastic!! I am a hopeless beginner, but I learn something important in every video.

And yet another great informative video. Thanks for sharing the knowledge.

I have never understood fully about movements with the ‘friction’ being elsewhere in the train and why. This helps start to explain that aspect. Thanks!

As a hobby watchmaker, it is so great that you a professional share insight and tricks of the trade that make it possible for us tinkerers at home. The things you would only learn in a school or working professionally. As a master Harley Davidson tech, trade secrets can be closely guarded, but I believe sharing knowledge is the best way to keep skilled trades going. Long comment short, I appreciate your content!

Very helpfull to understand the way a watch works .Thank you.

Thanks Kalle. For some reason I had a brain fart and couldn’t figure out the Elgin 288 running but the hand kept stopping. Da!!

Stumbled across your KZfaq channel a week ago, haven't stopped watching it since. I cannot believe how much information and knowledge you are imparting, fantastic! Thank you so for sharing your experience.

Thanks,very very interesting how it all works.Happy Holidays. Itzhac

Hahaha! LOVE IT! I just independently wrote a little piece about the *amazing* thing that is a cannon pinion from a Design perspective. Then I found this video. Wow! Similar minds!

Many thanks for this information! It was very halpful

Many thanks for your explanations, as always really clear. I do love when you realize the drawings on paper: they make things immediately clear. Please continue to make them. BTW in the old time, latin used to say " Repetita iuvant" that means "repeating does good"🤣

All cannon pinions I’ve seen so far have two indentations on opposite sides!? To increase the friction I (most often) use the Bergeon 4733 cannon pinion tightener. To remove the cannon pinion I prefer to use a vintage cannon pinion remover tool which is very efficient and convenient and also eliminates the risk of damaging the centre wheel pivot.

Another great video, Kalle! I’m still not exactly sure how much to lubricate for ease of setting the hands, without losing the friction fit between the center wheel and cannon pinion for accurate hand movement.

You are a excellent teatcher. Thanks Kalle.👍

The view out your windows at the shop looks nice. I think I would enjoy working there.

Thank you for sharing Good information

I love what a simple implementation of a clutch this is and yet it works reliably.

Thank you!👍

Great job mate!

I have never heard of all that before. Excellent detail. Thank you for sharing that about the cannon pinion. Regards Mark

Great video. I had exactly this problem today. On a Tissot 2571 the minute/hour hands would slow down or stop at various points but the second hand ran normally. Also the hands turned too easily using the crown. Not enough friction from the cannon pinion. I adjusted the cannon pinion as you demonstrated… perfect. Thank you for sharing this valuable knowledge. 👍

Good another Hammer time

Great, thank you

This was such a great explanation and demo. Thank you for doing this.

Hope you’re having a good time, you’ve earned it 👍❤️👌

Thank you for the video. It sounds like some friction is required but not enough to stop the two wheels from turning independently under a small amount of relative torque.

BRILLIANT, no other words for it ,Thanks

This explains a lot for me now 👌

Very helpful. I build clocks but not watches. Thank you.

Thank you v for the video! I compare the canon pinion with a permanent car clutch as it transfers power depending on the pressure applied.

Really helpful, thanks Kalle

Hello, great tips! Thank you!

Good vídeo for holidays

This was a great video. I learned a-lot. You explained it very well.

Great insights as always. I've learnt so much from you. Many thanks Kalle.

THANKS

On Seikos (and I realize as a European watchermaker you probably aren't familiar with them and even if you were they're too inexpensive for you to be servicing them), the second wheel shaft is hollow (which yours doesn't seem to be) and the 4th wheel shaft comes up inside of the second wheel shaft to turn the seconds hand.

Dankjewel Kalle voor de goede uitleg.

Well explained something that few mention for so reason.

I am working on a AS-1916, Completely torn down, cleaned, lubed, reassembled, the movement runs beautifully except for one detail, No hand movement. This is apparently one of those exceptions. Time to strip back down and figure out how to fix this issue.

Another excellent video! I once thought it would be a good idea to put a bit of grease on the center wheel pivot, to make it easier to install the cannon pinion. The watch was running perfectly but after full assembly the hands weren’t moving. As you said, the cannon pinion needs enough slip so you can set the hands but also enough friction so the center wheel can drive the hour and minute hands!

Just foun your channel. I am a beginner and am so happy I found you. Keep the videos coming. I just finished an Elgin 18S and the I think the cannon pinnion is too lose. I have the symptoms anyway, hands not moving but pocket watch is working well. Just +/- 15Sec but the hands move way too slow. This video is a beginners god send for his problem. Thank you. :0) Dan C.

Many thanks Kalle, excellent! I feel ‘almost’ that this was a video just for me:-). I’ve dropped some hints how useful this would be to me, and was it! Staking set, yes, I have one, I hope I have wats needed to have a go. Also the tip about other parts might have the friction fit, I came across this a couple of months ago, boy did that have me baffled for a couple of nights! And calendar advice, all cracking stuff. Many thanks!

I've got to get an orange pen! :)

Good show! Noticed the hairspring is oit of centre. 😬😁😂😜

Happy Holiday Kalle, as always the best place on KZfaq for all things chrono pornography. 👍🏼😆

Another enjoyable video thank you. A question regarding lubrication please. Are there any rules? Is moebius 8200 generally applicable? Will lubrication of the centre wheel pinion destroy the friction effect. Or. Is lubricant required to extend the life what are tiny metal surfaces rubbing together? being the interior of the cannon pinion indent and the centre wheel pivot notch? Thanks

Great video . Very interesting . In my case I have a Seiko 6923 movement . The seconds hand is working normally but the hour and minute hands do not move when the crown is pushed in . I can set the time normally when the crown is pulled out . Are these symptoms explained by a worn cannon pinion or a cannon pinion that does not have enough friction with the pivot of the centre wheel ?

How do you tighten the pinion type that is attached to the wheel, like the one you showed second? thank you

You forgot to mention the correct lubracation of the off center cannon pinon and in fact use some lube on the standard pinion.

3:37 This drawing is not exactly mushroom-shaped though; this detail would confuse neophytes.

Thanks Kalle, what type of tweezers did you use?

Oil on the cannon pinion ? I think I have committed a new guy error (on my first movement rebuild) and it is now slipping, probably because I got oil on it. Having seen this video I assume you never oil a cannon pinion and I need to take it apart, degrease it and put it back together dry. The movement itself is running accurately (software timegrapher says so) hence suspecting the cannon pinion slip. Paul

I have a 1920 French Open Face Hippolyte Parrenin Men’s Pocket Watch. The second hand run perfectly, but after an two or three hours both minute and hour hand stop while the second hand keep working. Do you have any idea why that is.

Its after midnight, and Im just fighting with Zeniths 2532C cannon pinion, thanks for your vid. Theres one other issue Im looking answer for, and theres nothing on the internet. The pipe in seconds hand is bit too short to reach second wheel pivot. Is there a way to extend the second hand pipe?

Can it be that not enough friction is the reason for loss of time (5 minutes a day) although the time grapher shows that the movement is about 300 seconds fast? My question remains and I still don’t have a clue……Can someone with watch experience pick up on my question?

is omega good or bad Chronoglide? My 8507 Omega is doing such strange things like : stoppping by itself when on low power reserve, immediately stopping for no reason. very confused but these videos are great to undertand movements better.

So, when you pull out the crown, set the time but when you push the crown back and the minute hand instantly jumps forward or back from where you set it.....that is because of a loose cannon pinion ?

With the cannon pinion being an interference fit device, where friction is vital, why is it lubricated when refitted after servicing?

Do you oil the cannon pinion outside? As general rule?

Be aware of your surroundings when watching this video, in public transportation for example, because each time he does the friction gesture some people might think it’s another kind of video. ;-)

Koekoeks klokken :)

Not easy to follow. Still dont get it, how this part actually works.

i know it's frowned upon but this is how i got in to watch modding and fixing years ago i brought a hublot with a asian 7750 clone movement on the the timergraph it was perfect but the hour hand was not moving now i know what i need to look at the small wheel with triangle on the top it must be slipping ¯\_(ツ)_/¯♥
