The Pro-Tek USMC 1200 Series 42mm Carbon Composite Automatic Dive Watch combines rugged construction, dependable automatic mechanical performance, and USMC-inspired styling in a purpose-built dive watch designed for demanding conditions.

At its core is a lightweight yet durable 42mm carbon composite case paired with a 60-click unidirectional ratcheting dive timing bezel. A 316L stainless steel screw-in caseback features an embossed USMC logo, while the 316L stainless steel screw-in crown incorporates multiple O-rings for added protection against water intrusion. The watch is water resistant to an impressive 300 meters, making it well suited for diving and other demanding environments.

A scratch-resistant sapphire crystal with antireflective coating provides clear, glare-reduced viewing while helping protect the dial from everyday wear. Illumination is provided by the Swiss self-powered Pro-Glo T25 system, which continuously glows for up to 25 years without requiring exposure to an external light source.

Power comes from a dependable Japanese Seiko/TMI 24-jewel automatic mechanical 3-hand and date movement, eliminating the need for a traditional battery. The genuine rubber strap features a steel signature buckle and incorporates a steel tube molded into the strap to provide additional strength and durability where the spring pins pass through.

With its combination of carbon composite construction, automatic mechanical movement, 300-meter water resistance, sapphire crystal, T25 illumination, and USMC caseback, the Pro-Tek 1200 Series delivers a rugged and highly capable automatic dive-watch platform.
