MWC "Depthmaster" 100ATM Military Diver Watch

Introducing the MWC "Depthmaster" 100ATM Military Diver Watch, one of our latest and most robust models. This 100% Swiss-made diver's watch is designed to endure extreme conditions, featuring a sapphire crystal and a 100ATM (1,000 meters / 3,280 feet) water resistance rating. It is suitable for diving with mixed gases at extreme depths and includes a wider 24mm bracelet and a non-scratch ceramic bezel, making it easier to grip in extreme cold. These watches are specifically crafted for professional divers facing very challenging conditions.

Helium Escape Valve

All MWC 100ATM models come equipped with a helium escape valve. This feature addresses the issue of helium molecules entering the watch. Helium molecules are extremely small, allowing them to penetrate the watch seals even when other gases and water cannot. This can occur in saturation diving, where divers spend extended periods at great depths under high pressure.

Helium buildup inside the watch can create internal pressure, potentially causing serious damage or even blowing out the crystal or crown when unscrewed. This is particularly dangerous during time checks or resets. The helium escape valve automatically releases these molecules during decompression, ensuring the watch returns to normal sea level pressure without letting any external elements in.

Importance of Helium in Deep Diving

Helium is crucial for deep-sea diving because it does not cause nitrogen narcosis, unlike nitrogen. Helium replaces nitrogen in most deep-sea mixed gas diving applications. Professional divers working at great depths for extended periods often live in dry environments pressurized with an oxygen/helium mix. Upon surfacing and decompressing, this gas must be safely removed to avoid potentially hazardous situations like the crystal or crown being blown out, which could cause injury.

Benefits of Sapphire Crystal

Synthetic sapphire is the best material for watch crystals due to its exceptional strength and resistance to shattering and scratching. These properties make it highly appealing to military and security personnel, police officers, and individuals with active outdoor lifestyles, accounting for over 70% of our customers. In comparison, over 90% of cracked crystal incidents involve watches with mineral glass crystals. Even hardened mineral crystals cannot match the durability of sapphire under adverse conditions.

Sapphire crystals are heat-treated to remove internal stresses, enhancing their strength. They are made with two layers of anti-reflective coating. Interestingly, sapphire crystal is now also used in the latest iPhone models. While sapphire crystal is more expensive, it is typically found in higher-end watches due to its superior qualities.

An excellent value for a luxurious long-lasting daily necessity
Scent: Lavender
Lovely soap with a pleasant fragrance and great lather. Real lavender buds give it an exfoliating quality without any roughness or redness. Product lasts and lasts so this crate is a true bargain. It truly is a 5 star product - I would give it 6 stars or more if possible. I use it for facial care and am very happy with the luxurious sensation of self-care every time.

Very good bar soap
Scent: Alpine & Spice
I have been using this bar soap for about two years now. I continue to use it because of the ingredients, the way it’s manufactured, and because of how it feels on my skin in the shower and afterwards. I have only used the β€œno grit” flavors. The scents are ok, nothing special or exciting. Some of them barely have any scent whatsoever, and some of them have a mild scent. But none of the flavors I have tried have a strong scent, and none of the scents are bad or offensive. The lather is excellent really good lather. My skin always feels clean, hydrated, and healthy after showering with all flavors of this soap. Love this stuff. Crate 61 customer support is excellent.

Great Soap. I spend about $75 for spa quality face wash because of my skin type but this works better and even calms my skin better. It smells great and can be used on the body and face. My skin loves it. I’m a customer for life.

great bar soap
Scent: eucamint
I like this bar soap. It lathers, cleans, and rinses effectively and does not dry out my skin. It exfoliates lightly. It's a decent size and shape bar that makes it convenient and easy to use. The package count is a reasonable 3 bars and the packaging in minimal. Its a well made bar of soap. And its plant based and natural. The scent smells great and is subtle and not perfumy. I'm a guy and this soap is great for me. I have long been on a quest to find a bar soap that doesn't dry out my skin and has a scent for a guy without being a stupid scent like burned wood, leather, tobacco, etc. Plus the bar shouldn't be so big and heavy that its difficult to use, to store, or breaks your foot if you drop it. I also don't want to have to buy 12 bars at once nor should it be super expensive. Plus has to be natural and biodegradable. I found a brand and bar that did all that and used for a number of years, but then they stopped making it. So, I went on a new quest of many different bar soaps and when I found this one, it checked all the boxes and expect it will be my new ongoing bar soap for years to come.
