I have a Link with a small second hand dial at 9 o’clock position, and a chronograph second hand on the main dial. As I never used the chrono, and the second hand is a bit too small to read. I’m wondering if I can just turn on the chrono and let it run indefinitely, that if synced well, effectively becomes the main second hand? Any issues with that? Would it drain the power reserve too much? Affecting accuracy? Any thoughts are appreciated. Thanks.
