The ANU stands for Authorized for Navy Use, a nod to the U.S. Navy’s classification for gear that has passed design safety reviews, testing and evaluation to ensure acceptability for use by the Navy. And what we are talking about here is acceptability for use by U.S. Navy divers and Navy SEALs. The Luminox brand was built on its affiliation with the Navy SEALs, and this Luminox ANU 4220 Series watch continues that tradition.
The ANU 4220 Series is a solid, no-nonsense watch, encased in tough stainless steel with a black brushed finish, that is ready for just about any environment. In fact, if you’re not sure what environment or elements you will be facing, select this watch when you head out. This watch will withstand whatever you throw at it. To top it off, a Sapphire crystal with anti-reflective coating will easily brush off just about any impact or scrape.
Combined with a rubber/silicone strap, this substantial watch actually feels light on the wrist. With multiple holes in the strap it’s easy to get a snug and tactical fit against the wrist. And since it’s rubber/silicone you want have to worry about injury to your wrist if the strap gets caught on something, an issue of concern with steel bands.
Where this watch really shines, in comparison to similarly designed tactical watches, is its phosphor-coated tritium tubes that mark each of the 12 hours, and also the hour, minute and second hands. So even if it’s zero dark thirty, you’ll still be able to see the time. And the luminescence doesn’t fade throughout the night (or day), it’s always glowing brightly. Only time (a decade or more) will diminish the glow. Only a handful of watch manufacturers use this technology, and Luminox is famously one of them.
If you have more than a few watches, this may be the one you select more often than the others. The Luminox ANU 4220 Series watch is solid, tactical, looks good, and feels good to wear. It’s a watch you can wear every day, or for those special days where you might find yourself knee deep and wrist deep in mud. Either way, you’ll get plenty of good use from this watch.
