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.

KEEPS MY ENERGETIC 1 YR OLD LAB BUSY
Size: Large
Anyone that has a field Lab knows you have to keep them busy which is difficult with the snow that won’t melt and the unusual -15 degree windchills we are having in NYC. Like others I’ve wasted so much money on various toys and puzzles trying to keep her busy and mentally stimulated. She either destroys them in minutes or won’t touch them. However, these with treats inside are fantastic. She loves the chicken flavor treats that go inside the ball. The treats for the holder are pricey but worth it so it keeps her busy for a while and she doesn’t get super hyper with cabin fever. Once I can get her back outside for longer periods to play and run off her excess energy I probably won’t be buying them on a regular basis given the price and that they only last a couple of hours given her strong jaws….Probably only for a special treat. However, for now they are worth every penny. The only con is they are difficult to get into the holder which is good so she can’t remove it.

We love em!
Size: Medium, Size: Medium
My dog loves these! I get a size smaller so it’s harder for him to eat. He’s 70lbs I get him the medium and it will last him 4 ish days. I also fuill the back with dog safe peanut butter, broken treats, and his food. This keeps him happy while I’m at work :) for reference he’s a gsd, and Australian shepherd mix. He never lets it get too far away, and proudly carries it along even when empty. He had one for over a year that just now started to break. They are very strong, great for chewers, and worth their weight in gold! When empty they also make them have the funniest faces🤣 again my dog had the first one for over a year before it started to rip. They are hardy.

Wrong item sent
Size: Small, Size: Small
The bento ball itself is great but the extra 16 treats that were sent as part of the purchase were the wrong kind. The picture used in the Amazon ad is the one shown in the left part of the picture I posted (dome shaped treats with a dog named Lacey in the picture), and what I received is shown in the right part of the picture (ridged treats with a dog named Bella in the picture). The problem with the Bella treats is that they are a bit smaller than the Lacey treats which means that they dont fit sugly into the bento ball. This in turn means that my little maltipoo gets them out of the bento ball in a few minutes. This defeats the whol purpose of the treat, and even worse this is a choking hazard for small dogs which makes the product unusable for me. FYI - I have never had this problem with the Lacey treats - they work great which is why I bought this product since this is what was shown in the picture. I sent a message to the vendor about this but have not heard anything back. Amazon offered to refund me half of the total purchase price if I sent back both the ball and the 7 of the 8 treat packages (I opened one only to discover this problem), which is also not great.

Fun, but short lived. Not tough enough for hard chewers
Size: Medium
Great idea. Wish it was tougher. My dog gets the branded treats out in ten minutes, and then destroys the ball in 30 minutes.

Best for my dogs
I’ve tried several coffee wood sticks for my dogs and these are by far the only ones they’ve liked and actually kept going back to! I have a terrier mix and a Pomeranian and both of them share it frequently!
