The Watch
Through its Khaki Field collection, Hamilton has crafted a lineup of watches with a quintessentially vintage, military-inspired aesthetic, powered by mechanical movements and offering outstanding value for money. It's one of Hamilton's most iconic and enduring collections to date. The 316L stainless steel case measures 38mm in diameter and just 9.5mm thick, making it a compact, discreet, and comfortable everyday wear. It's protected by a sapphire crystal, renowned for its exceptional scratch resistance thanks to its extreme hardness. The crown sits at 3 o'clock, as is traditional in watchmaking, and the screw-down case back ensures a water resistance of 5 atmospheres. In short, a refined and robust timepiece that pays the finest tribute to Hamilton's storied history.
The Dial
A military-style dial that prioritizes efficiency and readability without sacrificing visual appeal. Round in shape and black in color, it features three hands for hours, minutes, and seconds. The hour and minute hands are sand-colored and coated with a luminescent treatment for clear time-reading even in low light. Hour markers are pyramid-shaped indices paired with clearly legible white Arabic numerals, accompanied by a white minute track for added precision. A distinctive visual touch: a 24-hour military time scale at the center of the dial displays afternoon hours (13:00 to 24:00) alongside the main Arabic numeral indices. The brand's signature appears beneath the 12 o'clock index in elegant white lettering.
The Movement
When paying tribute to vintage watchmaking, you might as well go all the way. That's exactly the philosophy Hamilton embraced - delighting enthusiasts with a hand-wound mechanical movement at the heart of this charming watch. More specifically, it runs on an ETA H-50 caliber powering the hours, minutes, and seconds hands, with an impressive 80-hour power reserve.
The Bracelet
This model is fitted with a brown leather strap in a NATO finish, reinforcing its army-inspired style and wrist comfort. Subtle lighter-brown contrast stitching runs along the strap for added character. It fastens with a silver pin buckle. Note that the measured lug width is 20mm.
Water Resistance
With a water resistance of 5 atmospheres (50 meters), this watch is a solid introduction to the world of water-resistant timepieces. While it's not built for swimming, snorkeling, or scuba diving, you can safely forget to take it off in the shower. That said, our experts recommend keeping it dry whenever possible to protect its movement for years to come.
