I have three Breitlings and all the sapphire crystals are damaged somehow either by scratches or the anti-reflective coating warping. Getting these crystals replaced without breitling insisting on a full service has been impossible, even when the service has been done recently. Of note, I have many other watches and none of them have had crystal problems. Is this a known issue with breitling? Know anyone who might source and replace the crystals? Rumor has it breitling keeps their parts pretty well locked up these days
