Thank you for your feedback. Here is a video that should better explain the problem. The chrono's second hand in the video starts at 8 seconds, and finishes at 13 seconds.
Yes, when you stop the chronograph and reset it, the centre seconds hand is gradually moving further from the 12 o'clock position. Basically, push start, wait ~15 seconds, push stop, push reset, and the second hand resets ~1 second further away from 12 o'clock.
However, when you push to stop the chronograph, the 60 minute counting hand, and the hour hand, on the 12 o'clock subdial will continue to keep running. Because of this, it prevents the makeshift solution of stopping the chrono's second hand on 12 o'clock and never using the chronograph again. For example, I stopped the chrono's second hand at 12 o'clock, then went to sleep for 7.5 hours. When I woke up, the 12 o'clock subdial's hands were at 7:30. Pushing reset, both the 12 o'clock's subdial's hands returned to -1 minute.
Thanks again for your advice, 🤠
