Great experience!! Hector was great, he had the watch I was interested in ready to show and even did a new pressure test to ensure water resistance. Class act! Thanks Hector, and thanks Watchstox!!

A delightful buying experience. The watch is, as expected, in very good condition. Super-quick delivery so it arrived on time for my birthday. 10/10. Would buy again.
