SKU: 100ATM/12/PVD/QZ

The MWC "Depthmaster" range of Military Diver models represents MWC's latest heavy-duty collection. These watches are extremely robust, featuring a sapphire crystal and a 100atm water resistance rating, making them suitable for diving with mixed gases at extreme depths. They also come with a wider 24mm strap (most military diver watches use a 20mm strap) and a non-scratch ceramic bezel that is easier to grip in extreme cold. These watches are specifically designed for professional divers operating under very challenging conditions.

Key Features

Helium Escape Valve: All MWC 100ATM models include a helium escape valve. Helium molecules are among the smallest, allowing them to penetrate the watch seals even when other gases and water cannot. Saturation divers, who spend long periods at great depths under high pressure, are the primary users of watches with helium escape valves. Helium molecules can build up inside the watch, creating pressure that can damage the watch or blow out the crystal or crown. The helium escape valve automatically releases the helium during decompression, preventing such issues.

Importance of Helium in Deep Diving: Helium is used in deep-sea mixed gas diving because it does not cause nitrogen narcosis, unlike nitrogen. Divers in pressurized environments with an oxygen/helium mix need the gas to be safely removed during decompression to avoid injuries or damage to the watch.

Benefits of PVD Finish

The special covert matte black non-reflective PVD finish used for this watch is often specified in military contracts for special forces units, anti-terrorist units, and various covert operations. The PVD process creates a black finish on the steel that is vastly superior to painted finishes, which can easily fade or rub off. This PVD process means that the color of the steel is altered at a molecular level, ensuring it does not deteriorate even during heavy usage. However, the finish can be compromised if the case is severely damaged.

Benefits of Sapphire Crystal

Synthetic sapphire is the best material for watch crystals due to its strength and shatter and scratch resistance. These characteristics make it highly appealing to military and security personnel, police officers, and those who lead active outdoor lifestyles. These groups account for over 70% of our customers. Over 90% of cracked crystal incidents involve watches with mineral glass crystals. Even hardened mineral crystals do not match sapphire's durability under adverse conditions. Sapphire crystals are heat-treated to remove internal stresses, enhancing their strength, and are made with two layers of anti-reflective coating. While sapphire crystal is more expensive, it is typically fitted to higher-end watches and is now used in the latest iPhone models.

    An excellent all-weather option for all types of sleepers.
    Color: White, Size: King (102" X 90")
    I'm always freezing at night, but my boyfriend sleeps like a furnace. It's pretty difficult to find bedclothes that work for both of us. This comforter, however, is perfect. It's cool and light, not at all heavy, but it keeps us both at the perfect temperature. I was concerned that this wouldn't be enough to keep me warm in the frigid winter months, but our cold weather has finally begun and this has kept me comfortable throughout the night. I would definitely consider this perfect for use in all weather. One of my favorite things about this comforter is how well it holds up to washing. I just throw it in my washing machine on a normal setting and it cleans it perfectly. I bought this comforter in white, so a bit of bleach and it looks new and bright white every time. Unlike many comforters I've purchased in the past, this one doesn't bunch up on the inside after washing/drying. I've had several more expensive comforters that looked old and lumpy after one wash because the stuffing inside had all settled into different places, typically the corners or one side of the blanket, making it look ragged. This comforter has been washed 3 times since I purchased it and still looks just as good as it did on day one.

    reviewing 2 years later, still in love with this blanket!
    Color: Grey, Size: Queen (88" X 88")
    i've had this blanket for almost two years - i bought it july 5th, 2024. i should have wrote this review much sooner, there hasn't been a single day in the past almost two years of owning this blanket that i have regretted getting it, it is an absolute must have for hot sleepers. it isn't constantly cold, but it is cold to the touch and you'll feel how cold it is as you move around. it mainly helps regulate your body temperature throughout the night. i've washed and dried this blanket so many times (with cold water and low heat as directed) and it still maintains the cooling effect the same as the first day i got it, it also hasn't torn or ripped anywhere. whenever i travel i always miss this blanket and i am so happy when i come back home because i have my blanket again, it makes a huge difference for my quality of sleep. i'm genuinely considering only packing this blanket and nothing else the next time i travel. also, despite helping me stay cool throughout the night, it's very comfortable and has a nice thickness and weight to it, so i don't feel like i have to sleep with a paper thin sheet for the same effect. what i like to do during winter (and i'm talking actual winter, like wind chill in the negatives) is add a thicker blanket on top to get some extra layering, but still have the cooling effect. 1000/10 i absolutely recommend this blanket if you're a hot sleeper and honestly this company in general, bedsure makes some really good stuff! this was a really good investment for me, yes it's an expensive blanket but it pays off for sure. as a goth person i do wish they had some darker colors for this blanket, ideally black, but when this blanket has helped me this much with my sleep? i took the loss in that aspect, and if the color was the only loss i think that says a lot! thank you bedsure for helping me get good sleep :)

    Its not bad.
    Color: Green, Size: Queen (88" X 88"), Color: Green, Size: Queen (88" X 88")
    It is cool to the touch and when it warms up just move it around to a fresh spot, its comfortable. I thought i was purchasing the gel one so I was a little bummed out when it wasn't the same as my other one but thats on me. The product is thinner then the gel version but it still cools the same so im happy with that. When the box was delivered I was worried cause that packaging looked like it had been opened and closed back with tape as it was kinda just rolled up and shoved un the box but there is no rips, stains or bad smells. Over all I do like my gel version more then this one but it will be a fine substitute while that one is washing.
