Does the AP 15500 v3 instant date change happen at exactly midnight? Does the gen happen exactly at midnight? If a QC happens 5-10 minutes before or after midnight, is that a GL or RL?
Wondering how sensitive one needs to be on the timing of the instant date change for AP 15500s.
Btw, I am new to the forums, new to watches, new to replicas. I posted similar question in chatroom, so my apologies for re-asking.
1. You first need to differentiate between slow date change (date rolls for a time before changing over completely and instant date change (self explanatory).
2. Dates can instantly change at midnight or a few minutes before or after for the gen. The 0000 date change can be arranged with a hands reset.
3. Having a date change at 0000hrs on a given day may not mean that all 31 dates change at exactly the same time, especially for the rep where the associated parts are not as precise. You will still get instant date changes are different timings, variations likely within 1-3 min.
I hope this is clear for you. There is no reason to reject a watch based on the date change moment. If you’re concerned about that, be aware of what I wrote above, especially point 3 and make your own decision accordingly.
