Model PT4105SFC USMC Carbon Dive
Description
The ProTek Model PT4105SFC USMC Carbon Dive is a rugged, high-performance dive watch built for those who demand reliability in the harshest environments. Featuring a 45mm carbon composite case, 300-meter water resistance, and a 60-click unidirectional ratcheting bezel, this watch is engineered for serious divers, military personnel, and outdoor adventurers alike. Every watch is individually tested in both air and water to ensure it meets the highest standards before it ever reaches your wrist.
At the heart of this watch is the Swiss self-powered Pro-Glo T100 tritium illumination system, which glows continuously for 25 years without any need for an external light source - shining 100 times brighter than conventional photoluminescent lume. Paired with a dependable Japanese Miyota 2035 quartz movement and a genuine rubber strap with a reinforced steel buckle, the PT4105SFC delivers the kind of no-nonsense durability and readability that demanding conditions require.

FAQ
What is tritium illumination and why is it better than standard lume?
Tritium is a self-powered, radioactive isotope of hydrogen that emits a constant glow without any need for an external light source. Unlike photoluminescent lume - which must be "charged" by exposure to light and fades within hours - the Pro-Glo T100 tritium system on this watch glows continuously for 25 years and is 100 times brighter than conventional lume. This makes it ideal for diving, tactical use, or any situation where reliable, always-on illumination is critical.
Is this watch safe to use for scuba diving?
Yes. The PT4105SFC is water resistant to 300 meters, which far exceeds the depth requirements for recreational and technical scuba diving. It features a screw-in crown with multiple O-rings, a screw-in caseback, and every watch is individually tested in both air and water before shipping to verify its water resistance rating.
What does the unidirectional bezel do and why does it matter for diving?
The 60-click unidirectional ratcheting bezel allows divers to track elapsed time underwater. Because it only rotates counterclockwise, any accidental bump or knock will only make the time reading appear shorter - never longer - which is a critical safety feature. If your elapsed time appears shorter than it actually is, you'll surface sooner, which errs on the side of caution for air supply management.
How long does the battery last and can it be replaced?
The Miyota 2035 quartz movement is rated for a 4-year battery life under normal use. When the battery needs replacing, it should be taken to a qualified watchmaker or service center to ensure the water-resistant seals are properly reseated and the watch's water resistance rating is maintained after servicing.
What is the lug width, and what replacement straps are compatible?
The PT4105SFC has a 22mm lug width, which is a widely available standard size. This means you have a broad selection of aftermarket straps available - rubber, nylon NATO, leather, or metal bracelets - all in 22mm width will fit this watch.
