Omega mainspring winders

Omega doesn’t offer a specific winder for this series of calibers (they do for many others, but not this one). I service these all the time (have 5 in the shop right now) and I always replace the spring with a new one, as is standard practice.

The clearance between the outside diameter of the spring as wound in the shipping ring, to the inside diameter of the barrel drum is not large, so you really have to be careful to center the spring before you press it in.



You need to press the spring flush to the top of the shipping ring above the barrel drum, then move it back and forth to find the center before pressing it in. I also press the bridle portion of the spring in first, and only very rarely have I had one that doesn’t go in properly.
