I recently replaced the battery on my SNA411. At first, everything works fine. A few days later, the watch stops working. I replaced the battery again and had the same problem. After a couple of days the main and (hours, minutes) seconds dial stops work, but the chronometer still works. Every time I replace the battery, I have the same problem. I've even tried the AC reset method, but it doesn't seem to make a difference (in reality, I don't even know whether it is doing anything. There is no way to tell.)
Thanks for your help with this.
