I wanted to ask if anyone of you out there can help me out with my question about my Zenith annual calendar. (ref. 03.2072.4054/01.C711)
I noticed that the date and month switch over at precisely midnight. However, the weekday window is advancing at 3 am. My local watchmaker couldn't tell me if that's normal for this caliber ( El primero 4054).
Is there something wrong with my Zenith and does it need to be repaired?
Thank you guys in advance!
