Hamilton, a brand often celebrated for its robust military-inspired field watches and iconic designs like the Ventura, is now turning its attention to its adventurous Khaki Navy collection. For 2026, the brand has rolled out a series of updates to its Khaki Navy Scuba Auto diver and introduced new color options for the Khaki Navy Scuba Auto GMT, signaling a renewed push to distinguish these ocean-ready timepieces.
While the Khaki Field series often garners significant attention, the Khaki Navy line has steadily carved out its niche, embodying Hamilton's spirit of exploration. These latest revisions aim to enhance the collection's appeal, particularly in a market rich with compelling dive watch options.
The Refined Khaki Navy Scuba Auto: A New Wave of Design
The most notable changes arrive with the Khaki Navy Scuba Auto, the collection's three-hand dive watch. Hamilton has retained the familiar stainless steel case, measuring a versatile 40mm in diameter, with a 12.95mm thickness and a 50mm lug-to-lug dimension. The case features a brushed finish and maintains a practical 100-meter water resistance rating, complemented by a screw-down crown and a sapphire crystal with an anti-reflective coating.
A key update is the unidirectional rotating bezel, which now features refreshed typography on its 60-minute dive scale, housed within either a blue or black aluminum insert. However, the most significant transformation lies in the new dials. All updated Khaki Navy Scuba Auto models now boast a stamped, lacquered dial adorned with a distinctive wave texture. This decorative element adds a layer of visual interest, drawing parallels to patterns seen in other prominent dive watches.
Beyond the texture, Hamilton has standardized the dial design across all versions. Previously, some colorful models featured rectangular indexes, but now all variants share a consistent layout. This includes a combination of round indexes and wedge-shaped markers positioned at 12, 3, 6, and 9 o’clock. These wedge markers originate from within the rehaut, which also hosts the minute track, while the round indexes are placed slightly closer to the dial's center. The signature 13–24-hour scale, a subtle nod to Hamilton's field watch heritage, remains present further inward on the dial. A date window is discreetly integrated between 4 and 5 o’clock.
The hands, consistent with the previous generation, feature Super-LumiNova for legibility in low light, glowing blue. The tip of the seconds hand is rendered in red on the black, navy, and white dial versions, while the turquoise model foregoes this colored accent.
Powering the 40mm Khaki Navy Scuba Auto is the reliable Hamilton H-10 caliber. This automatic movement, a variant of the Powermatic 80, offers a robust 80-hour power reserve and operates at 21,600 vibrations per hour (3 Hz). It also incorporates a Nivachron™ balance spring, enhancing its resistance to magnetic fields, temperature variations, and shocks, contributing to improved accuracy.
These new models are available with either a 20mm stainless steel three-row bracelet or a rubber strap. The bracelet features a brushed finish with polished bevels on the central link, secured by a folding clasp. For those who prefer a rubber strap, options include black or turquoise, which taper from 20mm to 18mm at the pin buckle. The collection introduces several colorways, including a white dial with a navy bezel (H82425110), a navy dial with a navy bezel, a black dial with a black bezel, and a distinctive black dial with a turquoise rehaut and a matching turquoise rubber strap. The Khaki Navy Scuba Auto 40mm is priced at CHF 795.00.
Expanding Horizons: The Khaki Navy Scuba Auto GMT
Building on the success of last year's launch, Hamilton has expanded its Khaki Navy Scuba Auto GMT series with two new color additions. Unlike the updated three-handers, these GMT models maintain the dial design of their predecessors and do not feature the new wave pattern.
These GMT watches are housed in a more substantial 43mm stainless steel case, with a profile of 13.9mm and a lug-to-lug measurement of 52mm. They offer a greater water resistance of 300 meters, making them serious contenders for deep-sea exploration. The case is topped with a bidirectional rotating bezel, featuring a ceramic insert in either navy blue or black, which displays a 24-hour GMT scale. A bright red GMT hand sweeps across the dial, indicating a second time zone.
The new variants include a black-dial model with a matte texture and a black ceramic bezel insert, and a navy-blue dial version with a matte gradient finish and a matching navy-blue ceramic bezel. The dials feature the same style of indexes as the new 40mm Khaki Scuba Auto three-handers: mostly round hour markers complemented by wedge-shaped indexes at 12, 3, 6, and 9 o’clock. Due to the larger case diameter, the date window is positioned at 3 o’clock. The black version features a date wheel that matches the dial, while the blue version utilizes a white date wheel with black numerals. Notably, these GMT models omit the 13–24-hour scale, offering a cleaner dial aesthetic.
Driving the Khaki Navy Scuba Auto GMT is the Hamilton H-14 caliber. This automatic, caller-style GMT movement also operates at 21,600 vibrations per hour and provides an 80-hour power reserve, benefiting from a Nivachron™ balance spring for enhanced performance.
Completing the exterior, these 43mm GMTs are offered on a 22mm stainless steel bracelet or a black rubber strap. The bracelet, like its 40mm counterpart, does not taper, while the rubber strap tapers from 22mm to 20mm at the pin buckle. The Khaki Navy Scuba Auto GMT is available for CHF 1,275.00.
Charting a New Course
Hamilton's latest updates to the Khaki Navy Scuba collection represent a thoughtful evolution for the series. The 40mm Khaki Navy Scuba Auto benefits significantly from the new wave-textured dials and standardized index design, offering a more refined and cohesive aesthetic. The introduction of vibrant colorways, such as the black and turquoise option, injects a fresh, contemporary feel into the lineup.
For the Khaki Navy Scuba Auto GMT, the new black and navy-blue additions expand the collection's versatility, providing popular color choices for those who appreciate a larger, more robust GMT diver. While the 43mm case size and non-tapering bracelet on some models might appeal to a specific preference for larger watches, the overall enhancements across both lines underscore Hamilton's commitment to offering compelling options within the competitive dive watch category. These new models are poised to attract both long-time Hamilton enthusiasts and new collectors seeking a blend of adventure-ready functionality and distinctive design.
