Omega 286 barrel bridge

Hans64 · Jan 15, 2022

Hi all!

Is there a bushing on the barrel bridge for the barrel arbor? I got one that is really worned out. If I look on the bottom side I can se something the resembles as a joint but I'm not sure. I can clearly see that the center of the hole is oval and has lost its center so the staking set is not an option.

Thanks in advance.

I'm not seeing a part number for a bushing. Barrel bridge is 286-1001 though.

I rather not change the bridge since the serial number is stamped on it. I might even drill it out and put a jewel there instead. But thanks anyway.

Hi Hans,

Welcome to the forum!

I understand jeweling the barrel arbor port is not uncommon on Seiko chronographs.

No. If you are going to "drill" it out, you need to take care to make sure you pick up the center of the hole properly - the center of the original hole, not the enter of the worn hole.

That picture of the Seiko shows a pressed out bushing on the bridge. No drilling required for that one, simple exchange. The mainplate required drilling, however.

The Seiko jewels are made by a few people around the world for that specific purpose. Chances of finding a jewel to fit are slim to none. You would need to modify an existing bushing or turn up a new one.

This can’t be done in a jeweling tool as the hole has worn, you will need to do it in a lathe.
