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.

Best chew toy for a small dog
My Pomchi puppy was chewing on anything and everything, including me. He had a million other toys that he just didn’t care about. This is small and perfect for his tiny, ferocious mouth. It seems very durable so far and believe me, he doesn’t go easy on this thing. It’s hard enough that I can tell it feels good on his tiny, razor sharp teeth. The bone keeps him busy all throughout the day, and it doesn’t squeak, which is good because squeaky toys freak him out. I highly recommend this if you have a tiny, teething monster.

My puppies favorite bone to chew
I’ve bought at least a half a dozen of puppy bones for my doggie to try, the majority being from Nylabone, and the others from hartz. Her first bone was a pink puppy Nylabone xsmall sise. She definitely must have liked that one but unfortunately I felt like I had to take it away from her too soon, she was teething more then, but even so, thought it was unsafe when I saw little pieces come off and her trying to chew them. I really like these the best, though I don’t think I’ll be ordering any more at least not until she finishes her new ones. I don’t know what flavor she likes more, it might even be a color thing, but I think she prefers the orange ones which are peanut butter flavored. These are really ideal for toy breeds. My pup is still growing, she’s almost 7 months now, but unsure when she will stop growing, for reference she is a chocolate sable yorkiepoo, not sure of how much she weighs right now, but would estimate she weighs around 5.5-6 pounds. These are perfect for her, and I feel like they out live the other ones I’ve gotten, or she just has more interest in them. I bought a second package on subscribe and save (or possibly on my first and forgot I had a new order and didn’t return), but didn’t open the new package until recently as I felt the first pack were starting to look a bit knawed off, but in the middle there was still plenty of chew left. Oddly, she has prefered the old orange one vs the brand new orange one despite them being the exact same toy and flavor. I think she just hasn’t broken it in yet and I overloaded her with too many toys! I also got them for a great price, for some reason I noticed that the price increased nearly double of what I paid, and now they habe decreased a bit but still are about $2 more than what I paid. She loves all toys, and has many plush kinds. She still teeths, so when she is extra hyper and such, I feel like the bone helps occupy her for a moment. All in all I’d reccomend these out of any puppy bones to chew for toy breeds!

Love nylabones
Nylabbones did it again. The pugs love these. They're so cute and tiny. Perfect for their lithe selves. They're still safe and soft and very chewable.
