I am not lucky enough to own a Breitling, But my Brother in Law does. Like the advise already given make sure you send it off to Breitling. He was stupid enough to be tempted by the cheaper option and get the battery changed by an un-offical dealer. And in the long run to get the " mist " to clear and re- vacum it cost him alot more then it would normaly cost.
So what ever you choose just be carefull. You dont want such a nice piece of equipment to get damaged.
