Cannon pinion - The unsung hero in watchmaking

On request of foreign students I have made this video, so please forgive me if it is a bit repetitive but English isn’t their (nor mine) first language. The cannon pinion can cause many problems and defects in watchmaking, here are some tips and tricks!

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.

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 professional boatbuilder. When a project frustrates me it’s nice to look out at the water. The birds, fish, alligators and otters help to clear my thoughts

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!!

[johntebeau]

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!

[charlesstoeng]

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

[GrahamLeach]

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!

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!

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!

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

Stumbled across your YouTube 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.

[jefffoley]

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

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.

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

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

[marcop]

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.

[pacovalderrama]

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

[ianward]

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. 👍

[jlore]

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

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