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.

Great price great shoe
Size: 12, Color: Burgundy Polished Full Grain
Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.
