SKU: T100AT/1224/ST/SLA

The MWC Titanium Depthmaster is our latest heavy-duty professional dive watch and is engineered for extreme environments. Designed around real operational requirements rather than cosmetic “dive styling,” this model combines 100ATM (1000m / 3,280ft) water resistance, a sapphire crystal, ceramic bezel and always on GTLS / tritium illumination.

Unlike many oversized dive watches, the Depthmaster is built to remain wearable for extended periods. Large military watches are frequently manufactured in titanium to reduce fatigue — the reduction in weight makes a substantial difference when worn daily for long durations, particularly on a 47mm watch designed for all types of diving from Scuba to Saturation diving.

The watch uses a wider 24mm strap (most military divers use 20mm) for improved stability and security during active use, and the ceramic bezel offers excellent grip even in wet or extremely cold conditions.

This particular variant features a 24-hour military dial for quick time interpretation in operational or low-light conditions.


Tritium GTLS Illumination

The Depthmaster uses GTLS tritium tubes on the hands and markers. Unlike conventional lume, tritium does not require charging from sunlight or artificial light. The watch remains readable continuously, all night, every night and GTLS tritium tubes typically remain useful for about 20–25 years — making it especially suitable for military, security, aviation and maritime use.

The bezel markings additionally use Luminova for high initial brightness when exposed to light.


Helium Escape Valve (Why It Exists)

All MWC 100ATM models include an automatic helium escape valve.

Helium molecules are extremely small. During saturation diving, they can slowly enter the watch case while divers live in pressurised environments using helium-oxygen breathing mixtures. When the diver returns to surface pressure, trapped helium expands and can force out the crystal or damage the crown.

The one-way valve automatically releases the internal gas during decompression, preventing damage to the watch.

This feature is primarily required by saturation divers. Most recreational divers will never need it, but a true professional-grade deep diver must include it to be fully fit for purpose.


Sapphire Crystal

The watch is fitted with an anti-reflective sapphire crystal. Sapphire is significantly more scratch- and impact-resistant than mineral glass and far more durable than acrylic. In real-world service use, the overwhelming majority of cracked crystals occur on mineral or acrylic watches — sapphire dramatically reduces that risk.


Movement

The Depthmaster is powered by the reliable 24-jewel NH35A automatic movement with hacking function, allowing precise synchronisation.
Power reserve: approximately 41 hours.

Designed for Real Conditions

Professional divers, maritime personnel and military users often operate in cold, wet and high-pressure environments for extended periods. Watches in this category are intended to be reliable equipment rather than jewellery. The Depthmaster is built accordingly: high water resistance, continuous night visibility, shock resistance and simple operation while wearing gloves.

This is not a fashion diver — it is a functional instrument watch engineered for harsh service conditions.

Runs Small
Size: X-Large, Color: Black_a
I own several embroidered Western shirts by known manufacturers, including one purchased on Amazon. All are XL, and they fit fine. So I ordered XL on this shirt. I can wear it, but it's not a good fit or very comfortable. Specifically, it is a very slim cut - much slimmer than the dimensions given in the description state. So if you are a slim guy, no problem - order your usual size. If you are stocky, as I am, go up a size. In every other way, I really love the shirt - beautiful embroidery, very nicely made. I love the contrasting colors inside the collar and placket (inside of the snaps). I have re-ordered in XXL and hope and think this will fit fine. Not to figure out how to return this from the Philippines....
