Inspired by the diving pioneer John Lethbridge, The Winton Watch Company’s latest watch is equally at home under the sea as in the boardroom.


Hand assembled in Switzerland, the Lethbridge is a true diver's watch - water resistant to 500m, with sapphire glass, it will take pretty much anything you care to throw at it.


With a black dial, the timeless design features large ‘arrow’ pointers, making it easy to tell the time at a glance, and high luminescence means you can read it no matter what the conditions – whether diving wrecks or flagging a cab in the city.


The Lethbridge includes a ceramic rotating bezel – a feature introduced in the early 1950s to track a diver’s bottom time, or time spent underwater. The bezel can also act as a reminder to prevent divers from exceeding their diving time limit.


It’s sister watch, the Humphrey, has a blue face and is inspired by the daring rescue of British troops during the Falkland's conflict.

  • Who was John Lethbridge?

    John Lethbridge invented the world’s first underwater diving machine in 1715. A wool merchant based in Newton Abbot, Devon, he developed an airtight oak barrel with a small glass porthole that allowed the occupant to submerge themselves in water for around 30 minutes.

    The occupant of the diving machine lay on their stomach and put their arms through two holes with oiled leather cuffs that created an almost waterproof seal to allow the diver to work underwater. Lethbridge breathed the air sealed inside the barrel when submerged, and fresh air could be pumped in through a vent using bellows (with used air leaving through a second vent) when on the surface.

    During his first salvage operation using the machine, he recovered 25 chests of silver and 65 cannons.
