I have a watch given to me by my father (purchased in turkey) and it has a Miyota OT10 quartz movement with a chronograph dial. It hasnt been worn for some years now so i took it out of its box and baught it a nice new strap and battery so i could get some more use from it. Once reassembled i have found that the large (second hand) no longer moves with the chrono function and neither does the minute counter on the small chronograph dial (from what i remember the large hand would wizz round doing the 1/10 or 1/100th of a second). Im not sure the battery is the correct size (371) as the original was a 399, but as they are the same voltage should this make a difference?
Any help or advice would be greatly appreciated
