Hi, I sent my Aerospace Avantage to Breitling to get my first battery change. This was back in September 10 and since having back the watch seems to periodically lock with all the display illuminated. When I press the main control button it kick starts again, but this is obviously not supposed to happen. This has occur 4 times since September. I'm hoping that I can send it back to Breitling with the assumption that it is due to the battery change. Before I do that has anyone else either come accross this or experienced this fault. Thanks in advance.
