ProTek PT3102 – Titanium Field 3100 Series, Black Dial USMC Field Watch

The ProTek Titanium Field 3100 Series is designed for those who demand rugged reliability in a lightweight, field-friendly form. With its 40 mm titanium case (IP gun plated), flat sapphire crystal with anti-reflective coating, and 100-meter water resistance, the PT3102 offers toughness and clarity. The ProGlo™ T100 Swiss tritium tubes provide continuous glow, no need for external charging, delivering exceptional visibility in low light or dark conditions.

This variant features a crisp black dial paired with a black waterproof Italian leather strap. Its design balances purposeful simplicity with military aesthetic, the black tone gives it stealth and versatility, whether in duty gear or casual wear.

Powered by a reliable Miyota Super 2035 quartz movement with a 4-year battery life, the PT3102 is built for minimal fuss and consistent accuracy. Additional field-tested features include a titanium screw-in caseback embossed with the USMC emblem, a solid titanium crown with multiple O-rings, and robust hardware. At ~11 mm thick, 20 mm lug width, and ~48-49 g, it offers a comfortable wrist presence that doesn’t overwhelm.
