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.

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

Amazing - Stop Scrolling and Buy This Pillow
Size: Queen (Pack of 1), Color: White
I have been an Amazon customer ever since the very beginning, and this is my first review. Not because I haven’t purchased tons of amazing things (and a few bad ones), just never felt the need. However, I researched pillows for longer than I care to admit, and decided on this one. I’ve had it for about six months and absolutely love it. No lie, I genuinely look forward lying my big head on it after a long day. I am a side sleeper, but flip flop all around through the night and it’s great in every position. Pros: Stays nice and cool, which is soothing regardless of the time of year. Has a sort of quilted textured pattern on the zip up cover, gives it a luxury feel, that breaths nicely even when a pillow case is added. The fill is fully adjustable to your preference. I knew it came with extra filling but was worried it would not be enough. Wrong. It was very full and I ended up taking some out until it was perfect. It comes vacuum sealed and suggests it may take some time to fully take shape. However, I found it to be about 90% almost instantly and was sleeping on it a couple hours later. There was no unpleasant scent sometimes associated with memory foam items. The foam itself is very nice, a mix of what appears to be shredded and cotton candy cloud like. Very brilliant idea, as it is somehow supportive, soft and firm all at once. The affordability of this pillow compared to some of the others in this category can’t be overstated. Oh, and the packaging was very thoughtfully and securely done. If you are like me, an over thinker, I would suggest just taking this for a spin. It’s amazing. I’m not a bot, or working for the company. I’m just truly satisfied, love this pillow, and have been sleeping great.

It's the perfect pillow!
Size: Queen (Pack of 1), Color: White
I purchased this pillow specifically for its customizable fill feature, which allows you to add or remove stuffing to suit your personal comfort needs. Due to the unique curvature of my cervical spine—forward at the neck rather than backward—I require a soft, semi-flat pillow rather than one that is thick or firm. Additionally, I often experience ear discomfort by morning, so a gentler surface is essential. Upon adjusting the fill, I was pleasantly surprised by the generous amount of stuffing included. There was enough to fill an additional pillowcase, and I estimate it could easily create four to five more pillows. The ability to modify the pillow’s firmness at any time is an outstanding feature that makes it adaptable for a wide range of preferences and sleep styles. This pillow has exceeded my expectations in both comfort and versatility. I highly recommend it to anyone seeking a personalized sleep experience.

Good quality pillows overall
Size: King (Pack of 2), Color: White
Got a set of these for my wife and myself as we were struggling with our old pillows. These have some really good qualities and some things we'd like to see changed. First, the good: These are look and feel like they are high quality and made with good materials. The foam itself has a very nice feel to it. We love the fact they are adjustable to add or remove foam. They come with a pretty substantial amount already in the pillow. We appreciate the CertiPur certification. Now the improvements or changes we'd like to see: The foam, while feeling great, doesn't bounce back well if you scrunch your pillows, and so every day you have to fluff and reshape the pillow, moreso than some other memory foam pillows we've owned. One side of the pillow is cooled and you can feel that even through the pillow case, and that's a great thing. However, one side is not cooled and we'd have preferred if both sides were made of the cooling material. Overall, these are good pillows and we are not disappointed with the purchase. They are not, however, our perfect pillows (which do seem hard to find), and at some point in the future will probably make their way to the guest bedroom. We would rate them as some of the better pillows we've tried and feel most people would probably like them.

Perfect Pillow
Size: Queen (Pack of 1), Color: White
These are the best pillows ever. You can adjust the firmness or softness to whatever you want. For years i used a soft latex pillow , which you cant get anymore. I will never use another pillow. I have purchased 6 of these after the first one. You pick your own comfort level. Best ever. No more neck aches.
