I recently aquired these three Siro watches as a lot, couldn't find much about them until I removed the backs to find all the movements signed OWC and the small ladies case back signed ORIS WATCH COMPANY.
Does anyone have any information on the company and specifically this type of watch regards age etc, I guess 1940's?
the 'Dennison' type one runs for about 5-6 hours and the ladies (which needs a clean) is still running after 9 hours, the other 'military' lumed dial Gents does not run,I think the balance spring has gone.
As a newbie I am still learning but guess they are all pin/lever movements and not too valuable, but they look nice and are in vgc in fact considering their age I think other 'better' makers could learn a thing or two especially in terms of dial finishing as these are almost mint.
Thhe movements on both the gents are signed OWC CAL 296 SWISS MADE and the ladies is signed CAL 361 SWISS MADE but no OWC mark, this one appears to have at least 2 jewels.the other two perhaps just the one.
