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.

Durable against many rounds of zoomies
Strong bungee cord for sure, and my pup really likes pulling on it and playing tug with it. Originally bought it to encourage him away from underwear and socks, which almost worked. He likes chewing on the feet of the raccoon, so they’ve come off, but the lack of stuffing is wonderful. This is one of the longer lasting toys he’s had, and he’s had it for a couple of months, with its functionality still 100%. This seems to be almost like a toy within a toy, as you’ll still have the band when the rest is gone. Worth the money.

Cheap, and durable!
I bought this toy as a cheap temporary toy for my Rough Collie. Well, a month or so later, it's still alive. She has performed a 'squeakerectomy' on it, and it's lost it's springiness, but she still loves it.

Love the Stretch
I have two 15 ish pound dogs that love to pull and tug on this toy...all day long, every day. It's long enough for the humans in the house to also grab an end and not worry about getting nipped by playful pups. The fact that it stretches seems to be even more fun for the dogs. We have several other similar unstuffed long toys but they get very little attention. This toy is definitely unique and a cut above the other similar toys. The stretch seems to make all of the difference. If they had more animal choices, I would buy them all.

So cute!
Good size toy, but my 1yr old Jack Russell is NB match for it. It’s good quality and I’m sure it would last longer with a less aggressive chewer.

Dog loves it! Squeaky on both ends!
Bungee rope is not as resistant as I wished, but its fun nonetheless! Squeaks in head and tail. Misssteped the tail and broke one squeaker, still fun though! Toy can handle a beating. Really happy with it!
