Actually I was making appointment to send my Rolex 16758 GMT master for a service and during the process, I have casually asked if my Rolex 1665 DRSD can still be serviced? Rolex center then replied that it depends as they would need to seek verification from Switzerland. I have ,therefore, decided to send it for service and to seek verification. Since I’m planning to pass this watch to my son later on, I thought it will be good to have a watch with a record for him to keep. The watch has completed a complete service and it came with a service record card plus a chocolate… 😊
