I found some time to take a closer look on this watch, so here's another movement for you to see.
It is a 15 jewel Regina Watch Co. (Omega brand for American - mostly Canadian AFAIK - market).
It's a damaged and recased movement, but it has very nice dial, not bad plates and I bought it cheaply, so… why not having one?
Firstly - let's have a look at the setting mechanism.
This movement was made for American market, so it is set up for a male stem in the pendant.
As you'll see below - there are two levers, a circular spring and a pusher installed in the female half of the stem.
It is quite similar to Waltham's design, BTW.
The 3rd wheel dial side jewel had been crudely replaced and as I was to find out soon, the 3rd pinion is incorrect. It has 8 teeth, while I think it should have 10.
As a result - the hands move slower than the second hand - the minute hand will not advance a full minute when the second hand already finishes it's cycle.
At this point, though, I had no idea.
The ratchet wheel seems not original too. If so, than this is a functional replacement, in contrast to the pinion...
The watch has Swiss double roller escapement, Breguet overcoil hairspring and cut bimetallic balance. Good quality…
The dial is mounted with three screws on the side of the movement.
And that's it!
Like I said -mint PL dial on this one and lovely set of hands.
The watch is working, but - like I said - won't keep good time with incorrect 3rd pinion.
The movement is a mix of American style design features (like setting mechanism and balance jewels) with Swiss overall looks and finish.
It's a good quality movement as well.
The plating is already wearing off and I think it could have been thicker, though.
It is recased in Philadelphia Silverode case - the original probably scrapped for gold content.
I decided to leave it for now, maybe one day I'll find an original 3rd wheel for it.
I just don't have time to play with this watch anymore and - even though there are plenty of 10 tooth pinions around - I bet finding a correct pinion and fitting it would take hours of work…
Not worth it, I'll just sit back and wait, one day I will just find an original one to replace, as it's not a very rare model.
Thank for looking and... good day to you all!
