Hamilton Khaki Navy Scuba Auto GMT 43mm Mens Watch Black
Ref. H82555130
Sits in Hamilton’s upper tier here — more premium than three quarters of the Hamilton watches we list, which start at £375.
Price range £375 to £2,265 across 72 Hamilton watches in stock.The Khaki Navy Scuba Auto GMT arrived in 2025 as the travel-ready extension of a line Hamilton introduced at 43mm in 2021. The Scuba has always sat as the more accessible end of Hamilton's dive range, and the GMT complication here is a practical one: the red hand marks a second time zone against the bezel's 24-hour scale, while the bidirectional bezel itself adds a third — a genuinely useful arrangement for anyone crossing more than one region at a time. At 13.9mm thick the case is not especially slim for a diver, but 300 metres of water resistance with a screw-down crown and flanking crown guards means no concession has been made to keep it there. The applied hour markers — trapezoids at the quarters, dots elsewhere — are filled with light green Super-LumiNova and outlined in grey on this steel version, which keeps the palette controlled against the black dial. The H-14 movement underneath is an ETA-derived calibre shared across Swatch Group brands including Certina and Mido, offering an 80-hour reserve and a Nivachron balance spring that resists magnetic fields without needing a soft-iron cage. That reserve is genuinely useful on a travel watch; you can leave it on the nightstand for three nights and pick it up still running.

Learn more about Hamilton
Hamilton was founded in Lancaster, Pennsylvania in 1892, and its early business was the railroad. American rail accidents caused by unsynchronised timekeeping had forced the industry to adopt strict standards, and Hamilton built pocket watches accurate enough to meet them — earning the description the watch of railroad accuracy.
Two things then defined it. The first was war: Hamilton supplied over a million watches to American forces in the Second World War, suspending civilian production entirely, and its marine chronometers were fitted across the US Navy.
The second was electricity. The Ventura of 1957 was the first battery-powered electric wristwatch, and its asymmetric shield-shaped case, designed by Richard Arbib, looked like nothing before it. Elvis Presley wore one in Blue Hawaii.
Hamilton's cinematic presence is unusually deep — over five hundred films — and includes the watches designed for 2001: A Space Odyssey with Stanley Kubrick, and appearances in Interstellar and Tenet.
American manufacturing ended in 1969 as the quartz crisis approached. The brand was acquired by the Swiss and is now part of the Swatch Group, based in Biel, where it occupies a distinctive position: American design heritage, Swiss production, and ETA movements with long power reserves at accessible prices. The Khaki Field, descended from the wartime issue watches, is its best-known line.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 300m 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 comparedWhat 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 52mm, which suits wrists from roughly 17.5cm (7 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.
