Did I mess up the calendar on my vintage Omega Seamaster Quartz?
I recently bought a vintage Omega Seamaster Quartz and I think I may have done something wrong.
The first night I got it (around 10 PM) I wanted to set the day and date. Before using the quickset, I moved the hour hand to around 7 PM because I thought it was a safe time (that’s what I usually do with automatic watches).
Since then, the calendar seems a bit off. The date starts changing around 11 PM, and at 11:00-11:10 PM the date is already changed but the day is still halfway between the old and the new one.
The watch keeps perfect time and both the day and date still change, just not at the same time.
Did I actually damage something, or is this normal on these old Omega quartz movements? Is there an easy fix or should I take it to a watchmaker?
Thanks!
