Description

ProTek PT4109SFC USMC Carbon Dive Watch

The ProTek PT4109SFC USMC Carbon Dive watch is engineered for those who demand unwavering reliability and robust performance in extreme environments. This timepiece is a tribute to the United States Marine Corps, featuring a distinctive digital camouflage dial and the motto "SEMPER FIDELIS 1775-2025 USMC". It is ideal for military personnel, divers, and outdoor enthusiasts who require a watch that can withstand the toughest conditions.

Built with a durable 45mm carbon composite case and a 60-click unidirectional ratcheting dive timing bezel, this watch is designed for precision and resilience. The sapphire crystal with anti-reflective coating ensures clear visibility, while the 300-meter water resistance makes it suitable for serious diving. Powering the watch is a dependable Japanese Citizen/Miyota 2035 Quartz 3-hand movement, offering accurate timekeeping with a 4-year battery life.

Visibility in low-light conditions is paramount, and the PT4109SFC excels with its Swiss self-powered Pro-Glo T100 illumination system. This advanced tritium technology provides continuous glow for 25 years, 100 times brighter than conventional photoluminescent systems, without requiring external light charging. The genuine rubber strap, reinforced with a steel tube for added strength, ensures comfort and security during any adventure.

  • Durable Construction: 45mm carbon composite case and 316L stainless steel components.
  • Superior Illumination: Pro-Glo T100 tritium system for 25 years of continuous glow.
  • Water Resistance: Tested to 300 meters for serious diving.
  • Reliable Movement: Japanese Citizen/Miyota Quartz with a 4-year battery.
  • USMC Tribute: Features "SEMPER FIDELIS 1775-2025 USMC" on the dial.

How it works

What this watch’s key specs actually mean on the wrist.

Quartz

Quartz movement

A battery sends current through a quartz crystal that vibrates exactly 32,768 times a second, which the watch counts to keep time to within seconds a month — more accurate than almost any mechanical watch. Grab-and-go reliable: no winding, low maintenance, and years between battery changes.

300m / 30 ATM

Water resistance

Rated to 300m / 30 ATM — serious professional-diver territory. This is far more depth than daily life will ever ask of it, which is exactly the point: total peace of mind around water.

45mm

Case size

The case measures 45mm across (excluding the crown) — a bold, sporty footprint that makes a statement and wears best on larger wrists. Case size is the single biggest factor in how a watch actually wears, so it's worth picturing against your own wrist.

Carbon

Case material

Carbon composite is extremely light and shock-absorbing, with a marbled, high-tech look where no two cases are exactly alike. It brings serious-sports-watch DNA without the weight of metal.

Please note: international orders may be subject to customs duties, import taxes, or handling fees imposed by the destination country. These charges are set by your local customs authority and, where applicable, are the responsibility of the recipient.

Nick the owner was very attentive in answering my questions regarding the delivery of the watch. I didn’t realize I ordered it from somewhere international, but nonetheless it arrived with no issues perfectly packaged. Thanks Nick!
