The seconds hand on my Speedmaster has started to move in leaps of 5 seconds, which is usually a sign it needs a new battery.

I dutifully went to my first port of call in Brampton but unfortunately he doesn’t work on this model.

I could of course send it to STS. What is the hive’s opinion, the official or a serious independent?
I do not know the watch’s history.

Also, should I consider a gen 2 crown (but also keep the original) as pulling a gen 1’s hile wearing the watch is not exactly easy...

Over to you, with TIA.
