Hamilton has expanded the Khaki Navy Scuba family with new 40mm automatic divers wearing wave-pattern dials, alongside fresh steel Khaki Navy Scuba GMT models built for travel and water use.
The update keeps the collection in familiar tool-watch territory, but gives the smaller Scuba models more visual depth and the GMT range a cleaner steel-focused offering.
Wave-pattern dials reshape the 40mm Scuba
The Khaki Navy Scuba Auto 40mm remains the more compact and everyday-friendly side of Hamilton’s dive-watch lineup, with a stainless steel case measuring 40mm wide and 12.95mm thick.
Its 100-metre water resistance, screw-down crown, screwed caseback and unidirectional 60-minute aluminium bezel make it suitable for swimming, travel and casual recreational use rather than serious saturation-diving duty.
The main change is on the dial, where Hamilton now uses a stamped and lacquered wave texture in black, silver and blue, with thicker luminous markers and Super-LumiNova-filled hands improving the watch’s sportier character.
Five variants are offered, including black-dial models, a silver dial with a blue bezel, a blue-on-blue version and a more playful black-and-turquoise configuration on rubber.
The H-10 movement keeps the daily-watch argument strong
Inside the 40mm Khaki Navy Scuba is Hamilton’s H-10 automatic calibre, the brand’s 80-hour movement with a Nivachron hairspring for improved resistance to magnetism.
The date sits at 4:30, while the dial keeps a 24-hour scale that adds a practical field-watch note to the aquatic styling.
Bracelet versions use a three-row stainless steel bracelet with a folding clasp, while select black and turquoise-accented models come on matching rubber straps with pin buckles.
A steel return for the Khaki Navy Scuba GMT
The Khaki Navy Scuba GMT continues as the larger and more capable travel diver, using a 43mm stainless steel case that is 13.9mm thick and rated to 300 metres.
Instead of a conventional dive timing insert, the notched ceramic bezel carries a 24-hour scale, working with a red central GMT hand to display a second time zone.
Hamilton offers the GMT with black or blue dials, matched by polished ceramic bezel inserts, while the blue dial adds a subtle gradient and grained finish for a more contemporary look.
The H-14 automatic movement powers the GMT, again offering an 80-hour power reserve and a Nivachron balance spring, with date display at 3 o’clock.
Pricing and who these models suit
The Khaki Navy Scuba Auto 40mm is priced at CHF 795, EUR 895 or USD 975, making it a strong option for buyers who want a robust automatic sports watch with manageable proportions.
The Khaki Navy Scuba GMT is priced at CHF 1,275, EUR 1,445 or USD 1,525, with the black dial available on either bracelet or rubber strap and the blue version currently paired with the steel bracelet.
The 40mm models will appeal to those who want a straightforward daily diver with a little more dial personality, while the GMT is the better fit for frequent travellers who still want genuine water resistance and a sport-watch case.
