For more than 20 years California-based watchmaker Luminox has been working directly with some of the best maritime commandos in the world to shape and build its Authorized For Navy Use 4220 Series watch.

Making it on the ANU list is no easy feat. It means that Luminox’s watch is built to withstand the worst-of-the-worst k situations for soldiers on the front line, particularly the land and sea work done by America’s Navy SEALs.

The new edition of the Swiss-made timepiece from the American brand comes in the form of a black PVD stainless steel case with a one-way diver bezel that boasts a water resistance of almost 660 feet.

The 45mm anti-glare coated sapphire crystal domed case comes attached to a black rubber strap and is available for around $650.
