I own a Zenith El Primero Chronomaster with the display case back.
Unfortunately, for the second time since I've owned the watch, I dropped it on a hardwood floor.
The display window in the case back popped out both times. Both times I was able to hand press it back into the case back.
The first time, the window stayed in place for many years.
So I have two questions:
1. Is hand pressing the window back in sufficient or was I just lucky it stayed in for a long time?
2. Is a solid case back made for this watch?
If there's already a thread on these issues, please direct me to it - the search did not reveal anything.
Thanks in advance.
