Got a PO LM LE in April and the power reserve was fine, I forgot to wear it some days and watch would run even longer than 48 hours. Recently I was surprised it was stopped but I didnt think anything of it. But it stopped again before I thought it would, did some math and I'm now getting about 33 hours of reserve. Also notice it takes more winds to start it after its stopped, although just now it started again immediately when I picked it up. Time to service? And can I still wear it until it goes to service?
