Bremont Supermarine Chronograph 43mm Automatic Mens Watch
Ref. SUPERMARINE-CHRONO-BK-R-S
Sits in Bremont’s upper tier here — more premium than three quarters of the Bremont watches we list, which start at £1,950.
Price range £1,950 to £4,495 across 17 Bremont watches in stock.The Supermarine Chronograph sits at the intersection of two distinct worlds Bremont has long occupied: the diver's discipline and the pilot's instrument. The Trip-Tick case construction — a three-part steel assembly that isolates the movement within its own inner section — gives the watch its characteristic stepped profile and contributes meaningfully to how well it handles shock. The BE-54AE at its heart is a modified La Joux-Perret 7754, chosen and reworked for the calibre's vertical clutch architecture and column-wheel control, with an anti-shock mount added and a skeletonised rotor visible through the caseback. At 15.87mm thick it sits deliberately on the wrist rather than discreetly under a cuff, which is the honest consequence of housing a column-wheel automatic chronograph with GMT alongside a bidirectional bezel. The red-tipped GMT hand reads clearly against the black dial, and the bezel gives the watch a dual role that most chronographs in this class do not attempt. The rubber strap buckle uses a raised bridge design so the layered strap lies flat rather than bunching at the pin — a small detail, but one that reveals itself in daily wear.

Learn more about Bremont
Nick and Giles English founded Bremont in 2002, four years after their father died in a plane crash that Nick survived. All three had restored and flown vintage aircraft together, and the brand that emerged is inseparable from that. The name comes from Antoine Bremont, a French farmer who sheltered the brothers after an emergency landing.
Bremont set out to rebuild British watchmaking, which had effectively ended in the twentieth century. The early watches used Swiss movements in British-designed cases, with the Trip-Tick three-part case construction and a hardened outer barrel treated to over 2000 Vickers.
The military and aviation work is real rather than thematic. Bremont holds contracts with squadrons across the RAF, the US Air Force, and other services, producing issued watches for specific units, and has made watches for Martin-Baker ejection seat survivors — tested to the ejection forces themselves.
The company has also built watches incorporating material from historical objects: oak and copper from HMS Victory, aluminium from the Wright Flyer, and steel from Bletchley Park.
The manufacturing ambition advanced with the opening of a facility in Henley and the release of the ENG300 series in 2021, the first Bremont movement designed and largely made in England. Production is in the low tens of thousands annually.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 200m it is rated for swimming, snorkelling and recreational diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 42 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
22mm. 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 50mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's.
