I have the exact same problem. The watch must fit your wrist not vice versa. I have tried to get the 7727 to fit my wrist but it is too large. I have tried to get the 40mm 7140 to fit my wrist and it is too large. I have tried getting a 38mm 5277 to fit me and it was still too large. FInally I discovered any Breguet larger than 36mm would be too large for me due to its straight lugs. I wish you all the best!
