The ProTek Titanium Field 3100 Series is built for field-grade performance and premium feel. With its lightweight titanium frame, scratch-resistant sapphire crystal, and 100-meter water resistance, it delivers durability without bulk. ProGlo™ T100 tritium tubes ensure continuous glow, no external charging needed, for up to 25 years.

The PT3101BR variant features a clean black dial paired with a robust solid titanium bracelet with a signature clasp. The all-metal bracelet adds durability and a refined, earned presence on the wrist.

Designed for rugged conditions, it includes a screw-in caseback embossed with the USMC emblem, a screw-in crown with multiple O-rings, and a fixed bezel. With a weight of approximately 86 g, a thin profile of ~11 mm, and a 20-mm lug width, it balances strong wrist presence with long-term comfort.
