I just bought a Formex TS375 3751.3012 and everything seems perfect on this watch except for the chronograph. It has a 1/10 second dial which works fine, a minute hand on a 30 minute dial, which works fine, and then a small seconds dial for the clock which works, but activating the chronograph only wiggles the center sweep second hand. I got it to move a few times, but it mostly just jiggles so you can tell it's running, but usually doesn't advance. The minutes and 1/10 functions work perfectly, so the seconds are ticking off fine. I replaced the battery thinking that was it since it intermittently worked, but that didn't help (and I lost a battery retainer screw). Any idea if something like this would be fixable by a non watch repairman not afraid to get my fingers dirty, or a rough idea how much it would cost to fix. I found out this watch retailed for $1,200 to $1,500 and I only paid $60 at an antique store. I wouldn't mind putting a tad bit of money into it to restore it. Thanks in advance.
