Absolutely amazing piece you have there! You must be very happy to have it back - hope the service didn't take too long? It's definitely not one of the things I look forward to when it's time to send some of my watches off for service...
The purple strap goes very well with the rose gold case - a special timepiece calls for a special strap, that's for sure.
Enjoy your fabulous collection in the best of health!
Kind regards.
