Tudor FXD M.N.21
We are excited to bring to the market this sought-after M.N.21 Tudor FXD.
Tudor, along with Rolex, has a long history of producing dive watches, often supplying them to professional divers and military personnel to test these instruments to the extreme.
In 1961, Tudor became the official supplier of watches to the French Navy, known as the Marine Nationale. Fast-forward sixty years to 2021, and the Swiss watch company were once again called upon by the French divers to make a new batch of timepieces. The Tudor FXD is not just a commercial watch, but a tool designed by combat divers, for combat divers.
The unidirectional bezel has been swapped out for a bi-directional one, in order to time sections of swimming and aid in underwater navigation. The 42mm titanium case is lightweight and sturdy, and despite its fixed lugs and 52mm lug-to-lug length, it curves comfortably around the wrist. And it also offers a reassuring 200m of water resistance,
As you might expect, legibility is key and a matt blue dial contrasts against bold blocks of lumed indices and generously lume-filled hands – the snowflake hour hand giving a nod to the Tudor Submariners of the past.
The watch is powered by Tudor’s Calibre MT5602 automatic movement, which is not only COSC-certified but offers an impressive 70-hour power reserve.
But perhaps my favourite feature is the case back, engraved with the words “MARINE NATIONALE” and their anchor logo. A simple M.N.21 refers to the year this watch was produced, making it the rarest of all the FXD watches, as it was only in production for approximately 2 months in late 2021. A must-have watch for any collector.
Due to the watch’s fixed lugs (as requested by the Marine Nationale for greater security), the watch is supplied with a selection of five straps, perfectly suiting its adventurous design. The set includes two Tudor blue fabric straps (medium & short), one Tudor blue rubber strap, one Tactical Frog blue Tudor-style fabric strap and one Tactical Frog grey fabric strap, some of which are still unworn.
This special watch is presented in excellent condition, showing only very light signs of wear. It comes with its original box and paperwork, including a Tudor warranty which covers the watch up until December 2026.
