Vintage Chopard pocket watch LUC disassembly Part 2!

Part 1 of 2. This is my first shot at taking a watch apart to help learn how to service my own watches. I am learning from Mark Lovick of The Watch Repair Channel. These are great courses and I have learned a ton! This Chopard LUC pocket watch with Briguet overcoil hairspring in a silver hunter case (grouse stamping and hallmarks) with interesting features like Ancre Ligne Droite, Chaton jewels, Levies Visibles 2 Plateau, Balancier Coupe, and 15 Rubis, is a high-quality watch made around 1910, I think. I got it cheap, so I am risking very little if I screw it up :) ...Which I didn't do! Turned out that I was able to put it all back together and it kinda works. I need to take it apart again and do a proper job of oiling it. But I learned a ton! Music is ES_A Letter from the Caspian Sea - Daniel Kaede From Epidemic Sound

The star-shaped gizmo at about 12:30 is part of the stopworks, in this case a Geneva mechanism. Probably used in this watch to limit the running to the middle several turns of the mainspring. It looks like the mating part, which fits over the mainspring arbor square and rotates in the milled-out area of the barrel, is missing. Sometimes stopworks are found missing because a previous watch tech didn't know how to synchronize it. Or, the customer wanted the watch to run longer even though it would be fast at the beginning and slow at the end. The color of the jewels is mainly an aesthetic choice. Traditionally red in horology, due to about 1% chromium in the colorless aluminum oxide (corundum) base material. You ought to design a classy watch paper to put in the case when you're done!

Thanks for the information! Definitely going to find out about this...hopefully I will come across a watch with that mechanism in place so I can really learn about it first hand. Again showing my ignorance :0 I am not familiar with making a watch paper...Do you have a link where I can learn about this?? Really appreciate it!! Thanks for stopping by!

Good Geneva stopwork video: kzbin.info/www/bejne/omjGqnufqrCKq7s Searching the net for how to actually make a watch paper just results in ways to fold up an origami wristwatch. It's only a disk of paper printed with the name of your watch shop, service info, etc. and left inside the pocket watch. I made mine with Microsoft Paint, GIMP, and a color printer. Old watch papers are collectible all by themselves and it's a plus to find one inside a pocket watch. See www.americanantiquarian.org/watch-papers.

@@roygardner2374 Thanks for the links! I think the watch paper is a good idea! I will see about breaking out my vintage fountain pens and inscribing something interesting -- seems like this watch would like a hand illustrated paper :) Thanks so much for educating me on the Geneva stop, also! It makes lots of sense and that is a great video. I am really interested to see if my other pocket watches have that mechanism...Will definitely play with it to check the best power profile of the watch if it does. That is the kind of thing that my engineer brain likes to do :)

those European canon pignion can't be removed with proper tools since they don't have any edges to grab on , you remove them by gently hammering the minute wheel stem or by puling it off with pliers

[@ADudeAndHisWatches]

Thanks! That was definitely a puzzler :)
