A watch that was 'referred' to me by a member of our Polish Message Board.
So far I can only post this short video, detalied pictures - later, as I' not home today.
It's a fairly scarce Hamilton grade 939, No 15141, early double roller RR watch.
It was in bad condition when I got it - many scratches and surface marks, balance staff already repaired (good, easier for me), but balance badly timed (non original timing screws, shortened hairspring), and - worst thing - the pallet fork had a broken off exit pallet post (not just the pallet).
A new post had been soldered on by someone, but it would not work at all, so... I had to get a new pallet fork, and I could not find a counterpoised DR 18s fork. So... I made a good fork out of two different forks, thanks to American manufacturing system of the time ;)
Details - tomorrow, so 'stay tuned' ;)
