Help regarding pinion size


Goublin

Recommended Posts

Hi all,

 

complete noob here and just started my watch repairing/fixing journey. I have search the forum and online, but I’m struggling to find the information I need. I am currently working on fixing an old oris watch that was my grandads. Unfortunately for me the pinion on the third wheel went flying from my tweezers. I have had a good look, but it’s gone.

 

my question is, how do I know I’m ordering the correct size ? Any help would be really appreciated 

 

thank you

Hello and welcome to the forum. I don't want to appear unfriendly, but it's appreciated If you introduce yourself first, and then post in the correct section.

You need to identify the movement. There will likely be a number and a trademark symbol to be found somewhere, usually under the balance.

It would be nice for you to introduce yourself first, however to address your current issue you need to identify the caliber of the movement then you might be fortunate in finding a replacement in a material house such as Cousins.

You can't miss the Oris branding and caliber on barrel bridge of all in-house vintage movements. 

Oris later used Asian made movements which were branded for Oris.

A picture of the bridge layout helps identify the movement.

And Welcome to the forum.

    • Hello from the Mid-Atlantic United States. I've been in the hobby for a few months and have concluded that I will be staying in it for a while. I've started to get some proper tools and I am looking forward to developing some skills. My current goal is to get comfortable enough to service / repair some watches I've inherited from family members.  My current project is a Mentor pendent watch with a BF866 movement that belonged to my great aunt.
    • Success! The watch is working, albeit not perfectly. I need to install a new mainspring. It only runs about 16 hours. Still, it's my first cleaning and rebuild. I bought it from the original owner's son on eBay! The other one was bought at a flea market. I needed both to complete the project. The model with a seconds hand had soldered watch band pins and I couldn't drill tiny holes so I used the flea market Waldan, which was nearly a perfect match. I also replated the case with nickel, but the result was subpar. It's never as easy as it looks.
    • Thanks guys. It's a Seawolf 10ATM pre spring bezel. The case knife stressed me a bit, but eventually got it off and cleaned - nearly seventy years of grime.  Thanks.  Cheers John
    • Exactly. This is a pic of the hairspring I'm working on. My horizontal v vertical rates are all over the place. There is no discernible terminal curve. My problem is that the outer coil is (possibly) hitting the regulator pin. It's hard to tell but it looks to be getting very close. Also getting close to the stud, which could be @VWatchie's problem. You can see that I need to adjust the inner coil to centre the collet. That will hopefully solve the problem. But then I'll take the spring off and attach it to the cock to see how it looks.   I don't know if it's causing your problem @VWatchie, but I would say your inner coil looks like this
