The Watch
Housed in a 42 mm 316L stainless steel case, this watch captures the very essence of vintage American military spirit. The case is topped with a high-quality sapphire crystal featuring an anti-reflective coating for clear, comfortable reading in any conditions. The solid caseback is screwed down and transparent, revealing the rotor in motion. The crown is positioned on the right side of the case.
The Dial
Round in shape, this dial features a deep black color that contrasts elegantly with vintage-style beige hour markers. Every detail on this watch has been designed for an exceptionally clear, at-a-glance reading of the time. At 6 o'clock, you'll find a date window, and at 12 o'clock, a half-moon-shaped window displays the day of the week. Both subdials feature white text on a black background for instant legibility. The hands are silver-toned with sandy beige accents. Arabic numerals in the same sand color complete the vintage aesthetic - channeling the spirit of Lawrence of Arabia heading into the desert. A minute track in matching sand color runs along the edge of the dial. At the center, a second set of Arabic numerals (also in sand) marks the afternoon hours - a feature known as "Military Time."
The Movement
This timepiece is powered by the Hamilton H-30 caliber. Based on an ETA 2836-2, this Swiss automatic movement offers hours, minutes, seconds, day, and date functions. It delivers a power reserve of 80 hours, beats at 28,800 vph, and features 25 jewels.
The Strap
The watch comes on a sand brown leather strap with beige stitching, delivering a refined vintage look that's as pleasing to the touch as it is to the eye. Hamilton truly engages almost all the senses: the polished case to the touch, the movement to the ear, the elegant color palette to the eye, and the scent of fresh leather to the nose (the Ocarat team is still working on a way to bring a taste experience to watchmaking - stay tuned...). The strap fastens with a simple silver-tone pin buckle. Lug width is 20 mm. Strap reference: H600.705.119.
Water Resistance
This timepiece is not designed for diving or swimming. It offers 5 ATM water resistance, making it suitable for brief immersion but not prolonged exposure to water.
