OK I can't help it, I like to play with my watches, I hold, wind, clean, and check timing on each on a daily basis. I peek in their box and admire the gleaming metal and crystal curves with awe between handlings. I apparently put a lot of weight in how well a movement keeps and holds it's time.
Although I understand cleanly the specification and limits of mechanical movements I can't help but feel something is off with my beloved Omega Seamaster PO. Old stock but new, 2210-51-00 with caliber 3313. I've had it now about 3 weeks and it's seemingly getting faster and faster on a daily basis. In the first week it gained about 2 seconds a day...then 3 and now almost 6 seconds! I've tried varied resting positions. Fully winding every day. Running the chronograph or not. Allowing it to fully unwind it's reserve (which by the way was shorter than expected)
I am not sure if this works but I tried to check to see if it somehow became magnetized by using my iPhone compass and it didn't seem to be reactive.
What is a few seconds? Nothing really but the changing rate does concern me a lot. What are your thoughts?
