ProTek PT3103 – Titanium Field 3100 Series, Blue Dial USMC Field Watch

The ProTek Titanium Field 3100 Series is built for rugged day-to-day reliability with premium materials and design integrity. With its 40 mm titanium case treated with IP black plating, scratch-resistant sapphire crystal with anti-reflective coating, and water resistance to 100 meters, this watch delivers lightweight strength and clarity through the elements. The ProGlo™ T100 tritium tubes illuminate hands and markers continuously for up to 25 years, no external light needed.

This variant features a vivid blue dial paired with a waterproof Italian leather strap and titanium signature buckle. The blue face brings sharp visibility and contrast, especially in low-light conditions, while the black-plated titanium case adds a commanding, tactical edge.

With a secure design featuring a fixed bezel, screw-in USMC-embossed caseback, titanium crown with O-rings, and robust build details, the PT3103 is engineered for both performance and style. At ~11 mm thickness, ~48-49 g weight, and a 20 mm lug width, it offers a comfortable fit without sacrificing presence.
