I was working on this one tonight, came in a junk bag, along with a near identical, but lower jeweled donor movement with a better dial - whew!
In a Dennison Moon (20 year) case...
Swiss 15 jewel Movement Dominex As you can seen, no crown wheel (but the donor has one)
...and what do you know, it is yet another bridge variation of Marc's favourite movement. With the Patent number CH51482 (as usual). There is yet another small variation in the cover plate of the setting works, looks like a whale eating a dolphin to me. Someone was having fun in the design office that day.
The patented setting works:
The movement's setting works - as per the patent:
Houston, we have a problem (some bodger sheered the crown wheel screw off - did they not realise its a LH), photo shows after I've 1/2 extracted the screw.
It also had a broken case screw - poor thing.
Easy to get out though.
Under the barrel bridge is the old fashioned, Fontainemelon logo of an arrow through an apple - william tell.
The 15 jewel movement has 2 broken balance olive jewels, the 13 jewel donor has some rust. The 15 is negative set, as is the case - but I don't have an outer stem. Decisions decisions, burnished balance jewels are not fun...
You didn't think I was done did you? Nope. That's it for tonight.
