SKU Code: CH/500M/SS/SIL
Introducing the MWC 500m water-resistant diver watches with helium escape valve, part of MWC's latest elite range. These 100% Swiss Made watches are designed for both professional and recreational use, featuring:
- Impact-Resistant Sapphire Crystal: Ensures durability and clarity.
- Scratch-Resistant Ceramic Bezel: Ideal for a wide range of applications, from office environments to the most challenging outdoor activities, including professional diving.
- High-Quality Movement: Equipped with a 25-jewel Swiss Ronda R150 automatic movement, offering a 40-hour power reserve and a hacking function for precise synchronization.
Key Features:
Helium Escape Valve:
- All MWC 500M diver models come with a helium escape valve, crucial for saturation divers. Helium molecules, being extremely small, can penetrate the watch seals under high pressure. This valve allows helium to escape during decompression, preventing internal pressure buildup that could damage the watch.
Why Helium?:
- Helium is used in deep-sea mixed gas diving to avoid the negative effects of nitrogen, such as nitrogen narcosis. The helium escape valve ensures the watch remains functional and undamaged during and after deep dives.
Usage:
- While typical divers may not need a helium valve, it's essential for deep dive watches like the 500M range to ensure durability and reliability under extreme conditions.
Dimensions and Specifications:
- Movement: 25 Jewel Swiss Ronda R150 Automatic with hacking function
- Water Resistance: 500m / 1640ft
- Helium Escape Valve
- Crown: Screw Down Locking
- Case Width: 44mm
- Case Thickness: 13.4mm
- Crystal Type: Shatter and Scratch Resistant Sapphire with Anti-Reflective Coating

- Case Material: 316L Stainless Steel
- Bezel: 120-click unidirectional with ceramic insert
- Illumination: Swiss Super-Luminova C3 on markers and hands
- Strap: 22mm Silicone/Rubber
Benefits of Sapphire Crystal:
- Durability: Synthetic sapphire is highly resistant to shattering and scratching, making it the preferred material for high-end watch crystals.
- Strength: Heat-treated to remove internal stresses, enhancing its strength and durability.
- Appeal: Favored by military and security personnel, police officers, and outdoor enthusiasts. Over 70% of our customers belong to these groups.
- Comparison: While hardened mineral crystals are more durable than regular glass, they don’t match the durability of sapphire. The superior strength of sapphire is why it's also used in the latest iPhones and high-end watches.
These attributes make the MWC 500M diver watch an excellent choice for those seeking a robust, reliable, and stylish timepiece suitable for both professional diving and everyday use.

Try it but have lower expectations
Color: Black, Size: Queen
Pros:
-fairly heavy
-fits right
-soft enough to dream on
-not too expensive
Cons:
-kinda lumpy feeling and that’s hard to shake
-not the classiest wrap/attachment
-a little stinky out of the box that can take a while to offgas or whatever
It definitely upgrades a futon mattress, even if it doesn’t want to bend easily with it. It’s meant for a stationary mattress.

Feels Like Sleeping on a Cloud
Color: Black, Size: Queen
This mattress topper completely transformed my bed. From the first night, I noticed how much softer and more comfortable my mattress felt. The pillow-top design adds a plush layer of cushioning without making the bed feel overly soft or unsupportive.
I was especially impressed by how breathable it is. I tend to get warm while sleeping, but this topper stays comfortable throughout the night and doesn’t trap heat. The moisture-wicking fabric is a nice bonus and helps keep the bed feeling fresh.
The deep-pocket design fit my mattress perfectly and stayed securely in place without shifting around. Installation was quick and easy, and the black color gives it a sleek, premium look.
After fluffing up, it provided just the right amount of extra comfort and made my mattress feel much more luxurious. For the price, this topper offers excellent value and has greatly improved my sleep quality. I would definitely purchase it again and recommend it to anyone looking to add softness and comfort to their bed.

Feels Like Sleeping on a Cloud — One of My Favorite Bedsure Products Yet
Color: Black, Size: King
I’ve had really good experiences with Bedsure products over time, so whenever I get the chance to try another one I usually do, and this mattress topper definitely did not disappoint. This one went on my mom’s king size bed and the difference was noticeable immediately.
The topper has a soft, cloud-like feel while still giving enough support underneath so you don’t just sink straight through it. It added a much more comfortable layer to the mattress and made the bed feel cozy and inviting without being overly heavy or hot.
I also appreciated how easy it was to put on. The deep pocket design fit securely over the king mattress without struggling to stretch the corners, and once it was on, it stayed in place well through the night.
The material feels breathable and smooth, which is especially nice for warmer nights. My mom commented that she slept really well with it and woke up feeling more comfortable than usual, which honestly says a lot.
Overall this feels like a high-quality mattress topper that makes a bed instantly more comfortable. Bedsure continues to be one of those brands I trust for soft bedding and reliable quality.

Not Worth the Price
Color: Black, Size: Queen
I expected more. The images are a bit misleading with the amount of fluff and thickness the product actually has. Despite following the instructions, it’s pretty flat.
It had a funky chemically smell to it, so I sprayed with some Febreeze.
Honestly in my opinion I don’t think it’s worth $60. I think if you want something similar, go to Marshals or TJ Maxx.

Makes my camp mattress so much better.
Color: Black, Size: Full
I'm in a small motorhome and this has helped my sleep quality a ton. I got rid of my big mattress because the 2 camp mattresses I have are smaller in size, but a bit dense than the mattress I had. Uncomfortable for anyone that sleeps on them for long periods and when I come from biking or hiking the pain was making it hard to sleep. These have improved my sleep quality immensely. It also, to my surprise fit well, the cushions are only a few inches. These are up to 18, but the edge is nearly a perfect fit at the start. The straps keep it from moving. The length and width using 2 of the bed rolls is nearly perfect. On mattress the deeper part of the pocket, would fit perfectly.
The quality feels great, lightweight and washable, this is one of those items I wouldn't have likely ordered, but trying it is near priceless for my usage. Couldn't imagine how good it must be on a bed.
