I had an excellent experience purchasing my Audemars Piguet Royal Oak from Watch My Diamonds, and I want to give a special thank you to Mary and Daniel for making the entire transaction so enjoyable. When you’re making a significant purchase remotely, trust and communication matter, and they made me feel comfortable from the beginning. Daniel was very communicative, personable, and easy to work with. He sent clear photos and videos that accurately showed the watch and its condition. When it arrived, it was exactly what I had expected and in great condition. I really appreciated knowing that what I was seeing in the photos and videos was what I would actually receive. He also took my wrist size ahead of time and made sure the watch was properly sized before shipping it. It arrived fitted and ready to wear, which was a thoughtful touch. Being able to put it on immediately and enjoy it made the experience that much better. Daniel shipped the watch immediately, and his follow-through was excellent. The same care he put into communicating with me carried through to preparing and shipping the watch. Mary was also wonderful in helping facilitate the sale, and I appreciated how easy they both made the process. One of my favorite parts of the experience was that we even nicknamed my watch “the Unicorn” because of its rarity. That little detail made the purchase feel personal and memorable. It was fun to share the excitement of finding such a special piece with the people helping me buy it. The watch is beautiful, but Mary and Daniel’s service is a big reason I would come back. They made me feel valued as a customer, and the experience left me wanting to purchase from them again. Thank you, Mary and Daniel, for the great communication, accurate photos and videos, immediate shipping, and attention to getting the fit right. I’m extremely happy with my Unicorn and would highly recommend Watch My Diamonds to anyone looking for a special watch and people who make the buying experience just as enjoyable.

Designed in one night by Gérald Genta, the first Royal Oak model was presented in 1972 at the Basel Fair, after two years of development. This extraordinary watch elevated steel to a new status. By introducing the notion of "casual chic", it opened a chapter in the history of Audemars Piguet and Haute Horlogerie. Between 1972 and 1976, the Royal Oak 5402 was the only Royal Oak produced by Audemars Piguet, available in a single material and with a single dial. In four years, this radical model made its mark on the world before being rolled out from 1976 onwards in one of the most prolific collections in watchmaking history. This watch is a must-have for any serious watch enthusiast or collector.
Be advised, the dial has some patina signs which are normal due to its age. The watch itself has couple minor scuffs that can be polished off at your request. Sale comes with the original archive Audemars Piguet papers stated as original papers.
