While this is a ‘slightly’ older thread, I have had two GMT’s...
1st was dated 12/17, my current is dated 4/18. Of course, I have no idea of true build dates, but both gained about 30 seconds in a seven day period.
My current one is a mix of wearing and then on a winder at night in rotation with my sub. Set via the reference clock. 7 days later, it off over 35 seconds plus. My subc over the same time is like +1 or +2 max.
Brand new from an AD, both GMT’s exhibited this time gain.
FYI, they are both BLNRs
Any thoughts?
