I purchased a 2254 from the bay earlier this year. The seller stated watch was serviced in 2015 and provided spare parts to prove it. I hadn’t paid much attention to the accuracy until recently. I set the watch to my atomic time app on 7/15 this month. It fell behind a few seconds for a few days and slowly started gaining. I checked this morning (7/29) and found it was +3 seconds. Average that out and I have a watch that has run +0.21 seconds for 2 weeks. Curious to know what others have seen from this movement. I have a 2255 “electric blue” that runs a consistent +5 per day. Being that it is so consistent, I wonder if it too can be regulated to the same accuracy as my 2254?
Seamster Professional mid-size, checked at OB in June. .20sec per day. Was my watch for a year, then sold it to Woman to help subsidize a Speedmaster Pro. She dives in it regularly, as well as general, everyday wear. It doesn't get treated with kid gloves.
I’ve tried regulating my 2255 and can’t seem to get it just right. It either runs 5 seconds fast or a second slow per day. Either way it’s within COSC standards, but would love to see it run as good as my 2254.
