As 1916 Movement

Hello all. This is my first post. I got into watches last year. I have serviced several movements in the last few months. I learn something new with every one. I started with several ETA movements: 2801, 2824, 2836. Then I did several Tissot movements: 794 (3), and I just got a 796 that I haven't started on yet.

I am working on an AS 1916 that I got out of an old Carravelle. I am having trouble getting it to work. I cleaned and serviced it but the minute and hour hands won't move. I assume it is the large driving wheel or large offset wheel and pinion depending on who describes the part.

Any clues on how to proceed? Any chance of getting a new part?

Thanks.

Hi Scottster, welcome to the forum.

 

If you have got the watch running and the seconds hand is moving, but the hour and minute hands are not then the first thing to check is the canon pinion. 

try pulling the crown out to the setting position and see how easy it is to set the hands. If they move too freely then this would also point to a loose canon pinion, in which case you should be able to tighten pinion (carefully, and in tiny steps until it's right as it's difficult to rectify if you go too far) and restore the proper drive to the hour and minute hands.

Hi Scottster and welcome to the forum :)

 

From the information you've given Marc is spot on.  Tightening the canon is easy to get wrong, so as he suggested do it gently and in steps for your first attempt.

Don't panic however that all is lost if you go too far with it ... spares for AS movements are still easy to get from Old Swiss Watches, and Sudarson will offer you the right part for the right price ... highly recommended.

 

Remember, we only learn by doing ... and some of the best lessons come from our mistakes.

Thanks for the help. I will try to adjust the pinion and see how it goes. I will also see about getting a new part as well. Thanks for the help with the parts supplier.

ive got this problem on the as 1906, seems to be common with these, tighten the cannon pinion and all will be good.. if this is the case you can prob see that the hand moving is too loose..

Great advice. I figure if there is a way to screw it up I will. I contacted Sundarson and he had all the parts I need. He also had the parts for an AS 1803 I am having the same problem with. I can't wait to get them so I can get the Caravelle running properly.

Thanks for the advice.

      About repair watch's jewel.

      By jhoho202 · Posted

      First of all, thank you for the pdf file of the book on how to replace a gem. So, if there is a problem with the ruby in the movement, should I buy a new or used movement and replace it? When I watch videos on YouTube of people fixing used watches, I feel like there should be a way to buy a gem. Is there no way to buy it?

      Parts sourcing for FHF 180 movement

      By praezis · Posted

      I suppose @donutdan is not forced to earn his living by repairing watches.  I suppose he does it as a hobby and wants to gain experience, to get better in watchmaking and time is not the issue. Then @donutdan should rather try to repair the damage instead of swap parts from a maybe intact other movement. Swapping parts is not watchmaking. And often swapped parts are not the expected solution of all problems. All mentioned damages are repairable. Frank

      Yeah I figured that one out when I googled and realized that my spindle is actually from Horia. It's smooth with no screwable cap.

      Parts sourcing for FHF 180 movement

      I am puzzled by something a snipped out something from your image and what exactly disassemble tell us? my confusion is the symbol for FHF looks like image I have below year symbol as a star and righted this instant are not finding what that means? I suppose we could use the fingerprint system to verify it really is what it claimed to be. Size itself is really interesting there's almost no watches in that particular size. Then were missing details in the photograph above like diameter of movements to verify it really is the size and are missing the setting components.   went to the bestfit book looking at the symbols didn't see it. Look at the link below I did find it back to the bestfit book and yes it really is there https://reference.grail-watch.com/documents/history-of-ebauches-sa/ then bestfit book says lists the size as 10 1/2. one of the problems with vintage watches is finding parts yes a donor watch would be good.

      Oiling Dubois Depraz chrono module pivots (Omega Speedmaster Reduced)

      By Simeon · Posted

      Actually, this could be the issue. Drag from the module could be overcoming the cannon pinion. It was definitely not at the point that the driving wheel was loose on the cannon pinion, it took a little bit of effort to rotate it when applying the grease. Maybe I need to look again at applying oil to the pivots.    Yeah, it's very annoying. I don't want to give up on it, so back on with it over again until I catch a break.
