I recently bought JF diver chronograph with A7750 movement , sec at 3 located.
I found some weird situation such as
1. When I adjust minute hands I need to push the chrono stopwatch button, located 2 o'clock and adjust the minute hands. It is hard to adjust minute hands if I am not doing the steps what I said.
2. When watch stops, it is hard to restart.
It takes time to fully operate the watch.. the second hands is stop moving after few seconds.. but maybe 30 minutes later it seams working fine.
3. When I adjust minute, it has 2 minutes delay.
Is it something normal? Or should I send it back to JF?
Please help me out.
