ProTek PT3106 – Titanium Field 3100 Series, Sand Dial USMC Field Watch

The ProTek Titanium Field 3100 Series blends tactical functionality with lightweight durability. With its 40 mm medical-grade titanium case, flat sapphire crystal with anti-reflective coating, and 100-meter water resistance, the PT3106 is engineered for field use and designed to endure harsh conditions. ProGlo™ self-powered tritium illumination ensures visibility in darkness without charging, glowing continuously for up to 25 years.

This PT3106 variant features a warm sand/beige dial paired with a black waterproof Italian leather strap. The subtle tan face offers excellent contrast, while the black strap lends a rugged, versatile style, perfect for outdoor duty or casual wear.

Under the hood is a reliable Miyota Super 2035 quartz movement with about a 4-year battery life. With a titanium screw-down back embossed with the USMC emblem and reinforced hardware including strong case construction, the PT3106 delivers both performance and dependability. It sits at ~11 mm thick and uses 20 mm lugs, offering solid wrist presence without bulk.
