I'm reaching out because I've come into possession of a watch that was gifted to me, and I want to verify its authenticity. I've been doing some research, and I'm a bit uncertain whether my watch is an original product or just a master copy. Could you please provide me with details about the authenticity measures you have in place for the watches you manufacture? Additionally, it would be great if you could share any tips on how to distinguish between the genuine article and counterfeits. Your insights would greatly help me in determining the legitimacy of my timepiece. Thank you!
