Archer
··Omega Qualified WatchmakerOK...I realized that my magical 58 hour reserve happened because I absentmindedly wound the watch a couple times...
It is actually doing 45-47 hours per full wind, and loses about one minute over that time -
Is that accuracy decent? Based on this performance would a service be indicated?
Not enough information to say if a service is required, but it's certainly not keeping time well...
