Reference Guide
Ancienne Le Brassus celebrates the community spirit of WatchProSite by highlighting Marco 'Mstanga's' comprehensive guide to the Audemars Piguet Royal Oak Ref. 5402. This post not only reviews the guide's depth and detail but also underscores the generosity and camaraderie among collectors that makes such invaluable resources possible.
...and these shots are of course in hommage to Nico aka 'amanico' 
The Royal Oak reference 5402 is recognized as the original iteration of the model, introduced in 1972. This reference established the design language that would define the Royal Oak collection, characterized by its integrated bracelet and octagonal bezel secured by visible screws. It was initially presented as a luxury sport watch, distinguishing itself through its material and finishing in a period dominated by more traditional dress watch aesthetics. The 5402 was produced in various series, with the A-series being the earliest and most sought after by collectors.
The watch features a 39mm stainless steel case, often referred to as the "Jumbo" size, which was considered substantial for its era. It houses the self-winding Caliber 2121, a thin movement derived from Jaeger-LeCoultre's Caliber 920, known for its full-rotor design. The movement provides a power reserve of approximately 40 hours. The crystal protecting the dial is acrylic, and the watch offers a water resistance of 50 meters, suitable for general wear.
For collectors, the reference 5402 holds significance as the foundational model of a major watch series. Its various production series (A, B, C, D) present nuances in dial text and case back engravings that are closely examined. The integrated steel bracelet is an integral part of its design, contributing to its distinct profile. The blue dial, often with a "tapisserie" pattern, is a hallmark of this early reference, though other dial variations exist.
That doesn't surprise me; coming from him. Without forgetting to say that his work is great. Well done, Marco, and well deserved hommage to him, ALB. Superb thread. That is ALSO Watchprosite! Thank you. Nicolas
I loved to pictures, it makes me dream! I had a look at this work and it is a great indepth journey into the RO's history. I'm not surprised about the success the RO has in Italy as, as far as style is concerned, this country is a benchmark for good taste. In many sectors. Thanks for sharing. Cheers, Mark
mentioned by you: "This is what Italy is about, but also, this is what this forum, PuristPro also is about!" Bravo, bravo tutti! Enjouy your stay in Italy, but it doesnยดt seem very challenging to do so if I read you post and look at your pictures/viewes :-) Ciao, Oliver
Really enjoyed reading your thoughts and a very nice gift from Marco. My understanding was that the Royal Oak design was made after the Italian distributor conveyed to AP the need for a Sports Luxury timepiece in the Italian market, hence the deep love affair for it in Italy. S
Thanks to both of you gentlemen for sharing with us.
Yes, You're right! :) I forget that this is the actual url! Thanks for your kind reply and glad you liked the post ;) HAGWE, S
