My BR03 has been keeping amazing time up until recently. I was averaging about +- 4 secs a day, but recently it's jumped to around 10secs a day. No obvious reasons, just noticed my timepiece was further behind then normal over the elapsed days.
Anyone know why this might be happening or any quick fixes? Maybe it's just time for a service? Watch is only 3 years old.
Would appreciate any help from my fellow B&R clan.
