I own a Breitling Colt 2 Gmt auto and had several problems with Breitling UK.
I sent my watch in for an overhault and came back 4 months later ruined as the movement worked for a bit then stopped.
Once i've noticed this, i sent it back for another 2 months and guess what....same issue again!
I had to send it back and seriously complain. Two months later got it back with a brand new movement which works beatifully.
The moral of tge story is that Breitling Uk is not very good, charges people a lot of money and they took my watch away for 8 months before putting things right!
I would not recommend them!
