    Story

    History

    Tudor's link with the French Navy dates to 1956. That year the G.E.R.S. research group in Toulon received Oyster Prince Submariner references 7922 and 7923.

    Tudor became an official supplier to the French Navy in 1961 and held that status through the 1980s.

    The Pelagos FXD launched in 2021. It was developed with French Navy combat divers and has a 42 mm titanium case. The caseback is engraved M.N.21.

    What it brought to the industry

    The FXD name means 'fixed'. Its strap bars are machined into the one-piece titanium case, so the watch only takes single-pass straps.

    The bezel is bidirectional with a 60-to-0 countdown scale for timing naval navigation. WatchTime calls this unusual for a dive watch.

    Worn by

    • French Navy combat divers (Marine Nationale)The Pelagos FXD was designed for the French Navy's combat swimmers. The caseback carries the Navy's emblem.

    What is lug width?

    The gap between the two lugs that hold the strap, in millimetres. A new strap must match it exactly: 20 mm lugs take a 20 mm strap.

    Measure it in 30 seconds

    1. Take the strap off, or look at the back of it: many straps print their width.
    2. Measure the inside gap between the lugs with a caliper or a millimetre ruler.
    3. Round to the nearest whole millimetre. Most watches use 18, 20 or 22 mm.

    Strap, quick release or system?

    Most watches use spring bars, so any strap of the right width fits. Many smartwatches use their own band system instead, such as Apple Watch bands or Garmin QuickFit.
