Doxa Sub 250T GMT 40mm Mens Watch Grey Stainless Steel
Ref. 855.10.101V.10
Sits in Doxa’s upper tier here — more premium than three quarters of the Doxa watches we list, which start at £1,150.
Price range £1,150 to £5,215 across 36 Doxa watches in stock.Doxa built its reputation on dive watches for working divers rather than enthusiasts, and the SUB line has carried that ethos since 1967. This GMT variant extends it — adding a second time zone via a skeletonised GMT hand that sits over the dial without obscuring it, making the function readable rather than decorative. The cushion-shaped case, a house signature that distinguishes Doxa from the round-cased majority of its competitors, keeps the 40mm footprint compact against the wrist at just 10.85mm thick, sitting low enough that it does not catch a sleeve. The "Sharkhunter Vintage" treatment gives the matte black dial beige-toned lume on the markers and hands — a faux-patina finish that reads as genuinely aged at a glance without requiring an old watch to achieve it. The beads-of-rice bracelet is a period-correct choice for the aesthetic, and its folding clasp carries a ratcheting wetsuit extension: practical for anyone who actually intends to use the 250m rating over a drysuit. The Sellita SW330 inside is independently Swiss-made and built to be serviced without manufacturer involvement, which matters over the long term of a watch positioned as a tool.

Learn more about Doxa
Doxa was founded by Georges Ducommun in Le Locle in 1889, and spent its early decades on pocket watches and, notably, dashboard clocks for the emerging car industry — supplying Bugatti among others.
Its lasting contribution came much later. In 1967 Doxa released the SUB 300, developed in consultation with professional divers, and it introduced several things now taken for granted. The dial was orange, chosen after testing which colour remained visible longest as depth filtered out light. The bezel carried a US Navy no-decompression scale rather than simple minute markers, letting a diver read safe bottom time directly. The beads-of-rice bracelet included an expansion section to fit over a wetsuit.
Jacques Cousteau's organisation distributed the watches, and US Divers sold them in America. The SUB became genuine professional equipment rather than a dive-styled dress watch, and it appears throughout Clive Cussler's novels on the wrist of Dirk Pitt.
Doxa struggled through the quartz era and was largely dormant before being revived by the Jenny family, who reissued the SUB faithfully from 2002 onward.
The modern range remains almost entirely dive watches, with the same cushion case, the same bezel scale, and dial colours named for their depth-rating heritage — Professional orange, Sharkhunter black, Searambler silver, Caribbean blue.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 250m it is rated for swimming, snorkelling and recreational diving.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
How long does it run for when it's not worn?
About 50 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
18mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 42.9mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
