I recently had my 1965 Accutron with a 214 movement repaired with a sealed, new old stock, index wheel by a shop that said they knew Accutrons well and had sold them new when they came out.
But, the watch seems to like to stop and then start again, especially right after setting it. It will also sometimes do this when sitting still or when being put on the wrist.
When it stops, it still hums. The battery hasn't been replaced in probably about a year, but I thought maybe this stopping and starting may be caused by a low, dying, battery.
Any help or advice would be appreciated. I just payed a large amount to have the NOS index wheel installed, so I really would hope that it isn't the problem. Before I had the index wheel replaced, it didn't run at all and did not hum even with a new battery. I'm just not sure what's going on.
