The short hike up Mount Royal outside of Frisco, Colo., climbs about 1,600 feet in less than 2 miles. I’ll admit — on its face, kind of a strange testing location for a dive watch.
I looked down at the DOXA SUB 300 Sharkhunter on my wrist, and then at the surrounding mountains. “No,” I thought, “these mountains are as relevant as anywhere for a watch meant to do almost anything.”
While I’ve dabbled as a recreational scuba diver, the last month of life in Colorado hasn’t lent itself to much deep-sea exploration. But that didn’t stop me from strapping on a unique, historically relevant dive watch from the brand Doxa for some long days on the trail in the high mountains. And given the rarity of divers using analog watches in the era of computers, I feel confident that the Sharkhunter’s mountainous trials gave me a good send of this pretty, functional timepiece.

In short: The DOXA SUB 300 Sharkhunter has a unique appearance and rides very nicely on the wrist. It is both very comfortable and visually arresting, a great combination for a watch that, for most, will be worn with dress clothes and T-shirts more often than neoprene. But it does have real dive chops, with a 300m water resistance, good legibility, and a very utilitarian bezel and strap.
