I have a Perpetual Calendar Titanium 8F32-0049. Around 6 weeks ago I advanced the time by one hour when travelling from GMT to GMT+1. I advanced the time around mid-afternoon GMT, so well before midnight and date change-over. Since then, the time shown has been correct but the second hand advances in 5 second bursts and the date has remained frozen on the date that I advanced the time. I am sure it is not the battery. Any thoughts out there?
