SKU Code: SUA/SLSSBB/MY

This durable 300m water-resistant watch is specially designed for divers and general marine applications. Its ceramic bezel features high-visibility numerals, and the dial is exceptionally clear and easy to read, even in low-light conditions. The watch is equipped with Tritium GTLS (Gaseous Tritium Light Sources), which are significantly brighter than conventional luminous watches.

The timepiece features a high-quality 21 Jewel Cal. 8215 Automatic Movement and is water-resistant up to 30 ATM (1000 ft / 300m). Both the case and bracelet are crafted from stainless steel.

The military-grade sapphire crystal is highly scratch-resistant, with two internal layers of anti-reflective coating. The dial includes a radioactive tritium symbol. Tritium is a radioactive isotope of hydrogen, emitting beta particles that cannot penetrate skin, plastic, or glass. While the vials contain radioactive gas, the total amount is well below the personal limit of 25 millicuries, as specified by the U.S. Nuclear Regulatory Commission (10 CFR 30.15).

Why Choose Sapphire Crystal?

Many customers inquire about the benefits of sapphire crystal compared to standard mineral crystal. The key advantage of synthetic sapphire is its strength. It is shatter and scratch-resistant, making it ideal for those in military, security, or outdoor professions. Over 70% of our customers come from these active fields.

When accidents occur, over 90% of cracked crystals are mineral glass. Despite our use of hardened mineral glass, it still doesn't match sapphire in terms of durability under harsh conditions. After sapphire is manufactured, it undergoes heat treatment to remove internal stresses, making it incredibly strong. The result is a material that is not only highly durable but also resistant to scratches.

Interestingly, sapphire crystal is now also used in high-end products like the latest iPhones. However, because of its cost, sapphire crystal is typically found in higher-end watches.

Weird sizing
Size: 5-6, Color: Charcoal
Weird sizing/ fit! It says that they run large in length, so I got one group-size down (5-6). (The sizes are in ranges rather than specific individual shoe size numbers). I liked the concept of the suede reinforced toe & heel for longevity. My heel and toes cleared the length/width comfortably/well and the overall width was more than adequate, yet I found them to be rigid-stiff- tight (to the point of cutting off circulation) specifically in the toe. Ok, I knew that was a possibility BUT……while the toe area was tight the ankle and calf were HUGE and would not stay up unless I wore over pants, defeating the purpose of a slipper-sock. The inside cushioning was soft and comfortable. When I walked, my heel would slip out over the sued area, into the wool sock parentheses, making it awkward to walk. Returning…No point in changing sixes, as if I get a larger foot size, the tow may fit better, but the ankle will be beyond too big. Sigh. Unfortunate, as the concept is sound….the manufacturing/sizing is bizarre. BTW : I have normal width feet (not wide or narrow) and my ankles and calves are on the thinner side. The fit may be better suited to people with wider ankles/calves????

So cute
Size: 8-9, Color: Charcoal Faux Fur
These boot slippers are super cute and comfy warm. Fit true to size. Inside is real soft and warm. No, they do not offer support....they are slippers after all. The fur does not go all the way around the back. The back is just the woven sweater material but I imagine they would have zero stretch if the fur went all the way around. It may not be as cute without fur all the way but they probably wouldn't stay up if they didn't have the stretch material in the back so your only choice would be to let them slouch. I can pull them all the way up and they stay, I can do any degree of slouch and they stay so I see this feature as purely functional. Love the 2 tone with the suede around the toe and bottom but this is where my only complaint comes in is the sweater material right above the suede toe looks puffy so that part looks a little silly but otherwise they are absolutely adorable, comfy, warm and as functional as a pair of slippers can be. I wore them out in light rain and my feet stayed dry. The bottoms are like a rubberized fabric so they may soak through if you're in constant wet. Traction is surprisingly good even though it doesn't have a lot of tread. Overall i love them.

The answer to calloused feet.
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.

Slippery when wet!!!
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
“These moisturizing slippers are actually really comfortable and feel great on the feet. They’re soft, cozy, and do help moisturize while you wear them. I also think they’re a good value for the money. The only downside is that once your feet get moisturized, they can get slippery inside the slippers, so I wouldn’t recommend walking around too much in them. Better for relaxing and letting your feet soak up the moisture than for being up and moving around.”
