This classic hand-wound, 24-jewel MWC military watch, inspired by the 1940s/1950s design patterns, features a Swiss Sellita SW216 movement and a small subsidiary dial second hand. It retains the original appearance of the watches used by the British military during that era, while the improved water resistance of 100m (330 feet) and the shatter and scratch-resistant sapphire box crystal enhance its durability. Despite these enhancements, the crystal maintains the look of the original plexiglass without its drawbacks. 

This watch boasts a heavy stainless steel satin finish case made from Military Grade 316L stainless steel, a subsidiary dial second hand, a screw-down crown, a hacking function, a black dial with luminous markings, and a historically accurate canvas strap reminiscent of the 1940s and 50s.

The final image showcases the original 12 watches produced by companies like Buren, Cyma, Eterna, Grana, Jaeger-LeCoultre, Lemania, Longines, IWC, Omega, Record, Timor, and Vertex. MWC, founded in 1974, was not among the original manufacturers but this watch captures the spirit of the originals.

Benefits of Sapphire Crystal:

Many people ask about the advantages of sapphire crystal over the original plexiglass. Synthetic sapphire is the superior material for watch crystals due to its strength and resistance to shattering and scratching, making it ideal for military and security personnel, police officers, and active outdoor enthusiasts, who comprise over 70% of our customers. The original plexiglass crystals, made of plastic/acrylic, were prone to scratches and cracks and limited the water resistance of the watch. In contrast, sapphire crystals are heat-treated to eliminate internal stresses, enhancing durability. Two layers of anti-reflective coating are then applied. Although sapphire crystal is more expensive, it is typically found only in higher specification watches.

Swiss Sellita SW216 Movement Winding Guidelines:

To wind the SW216 from an empty state to full, you'll need approximately 20 to 25 turns of the crown, which is significantly less than most other hand-wound watches that require 30 to 40 turns. Once fully wound, the watch has an average power reserve of around 42 hours. Be cautious during the winding process, as securing the locking crown adds an additional 3 to 4 winds. This feature, designed to enhance water resistance, is uncommon in most hand-wound watches of this type.

For daily wearers who wind the watch every morning, a slight variation in the number of turns will not significantly impact the power reserve, as it will remain well below the maximum of 42 hours. Some users report that 15-17 turns are sufficient when winding every 24 hours, which is logical since the watch wouldn’t need a full wind after 24 hours. Most owners develop a sense of the optimal winding routine within the first few days of ownership.

It's crucial not to overwind the watch, as this can cause the mainspring to lock up or break. Overwinding occurs when a mechanism is wound beyond its designated stopping point, posing a risk of damage. Adhering to the recommended winding procedures ensures the longevity and proper functioning of the timepiece. Note that overwinding is a concern primarily for manually-wound watches, not for automatic ones, which cannot be overwound.

Dog approved.
Size: X-Large, Color: Cheese
I’m a 70 lbs Goldendoodle (supposed to be 65, don’t ask) and I love cheese. Real cheese. Sharp cheddar with sourdough bread is my dream, but apparently I’m “on a health journey,” so my people bought me this instead. Does this bone actually taste like cheese? No. I am not fooled. Do I still enjoy chewing it loudly while my humans are trying to watch TV? Absolutely yes. This bone satisfies my need to chew and my emotional desire for cheese-adjacent activities. It keeps me busy, saves the furniture, and lets me crunch dramatically during important dialogue scenes. The yellow color is nice — very cheese-coded — although some cheeses are white, so just something to consider for future versions. Also, good news: it doesn’t smell like cheese at all, which my humans seem very grateful for. Apparently they don’t want the carpet to smell like a deli. Weird. Final verdict: Not cheese. Still enjoyable. Would chew again. ~Barley

Withstands big dog
Color: Green Cactus
As a dog mom to two active pups, I’ve gone through a LOT of chew toys over the years and honestly, many of them just didn’t hold up. Some cracked, broke apart quickly, or became rough after only a short time of chewing. That’s why I was genuinely impressed with the MewaJump chew toy. Both of my dogs immediately loved it, and what stood out most to me was how durable it’s been compared to other toys we’ve tried. It’s held up really well with aggressive chewing while still seeming safe and comfortable for them to use. I also love that it keeps them entertained and engaged longer without constantly worrying about pieces breaking off. Definitely one of the better dog toys we’ve added to our home lately and Molly and Piper would agree.

Not recommended for strong chewers.
Color: Green Cactus
There was nothing wrong with this. But my dog is an absolute destroyer. She makes it her personal mission to annihilate any toy I buy. This did not last 30 minutes. Very cute and good for normal dogs that like to actually have toys to play with. Do not recommend for strong jaw destroyers.

Durable for light to medium chewers - not heavy
Color: Green Cactus
obviously cute. not super durable - lasted a good minute but disintegrates fairly quickly and eventually nothing was left - having to high monitor with a big chewer. (10 mo Great Dane)
