I got my watch around a month ago now & I've just been away for Christmas & New Year, with Gala Dinner. I've got Omega Cufflinks with orange incerts, coupled with this watch looked brilliant. I'm certainly not a shy type of person, £500 Union Flag shoes etc. Lol Anyway, since getting this watch I don't thnk it's lost or gained any time, at least to the naked eye. I've never adjusted it, so I'm surprised. My first automatic watch so I guess I didn't expect it. Is there a way to measure accuracy? It's not something I'm concerned about, I'd just love to know.
