D4 Outerknown USA Solar Diver

SUMMARY: The D4 Meridian is a historically-inspired 20ATM dive watch, that stands out in the Vaer line-up thanks to its perpetual solar-power movement and accessible sub-$600 price point. As a D4 model, this watch is the solar-powered version of our popular 20ATM professional-grade diver. In our opinion, the solar movement provides the best of both worlds - perpetual timekeeping with incredible accuracy. Six hours of sunlight will provide six months of power reserve, and the watch can run off any light source (even candlelight).

WHO IS THIS WATCH FOR? We recommend the D4 for those seeking a dependable ocean-oriented tool watch that can also be dressed up for more formal occasions. The perpetual timekeeping function of a solar-powered quartz watch makes it the perfect fit for an everyday wearer, and the choice of 38mm case sizing provides an option for most men's wrists while also maintaining our commitment to ergonomic, and timeless proportions.

INSPIRATION: In designing the D4 Meridian our goal was to pay homage to the history of military dive watches while also further establishing a distinct and modern Vaer aesthetic. This watch's dial design and bezel are inspired by Rolex and Doxa military divers from the 1970s - and the case is inspired by the military issue Omega Seamaster. The D4 Meridian Solar is further distinguished as one of the first Vaer field watches powered by ambient light - a premium feature that optimizes its use in remote settings and helps deliver on the promise of near-perpetual timekeeping.

This watch is sized at 38mm in diameter, and measures 46mm from lug to lug, giving it a small to medium-sized presence on the wrist, and complementing most men's wrists under 8 inches. The 38mm case is our smaller sized dive option, and we recommend it for anyone with wrists in the 6.5 inch to 8.5-inch range, or especially if you're someone who likes a more low-profile vintage fit (compared to our larger 42mm dive case options).

Built for extended outdoor use, this watch has been designed to be slim, lightweight, and as comfortable as possible, while still maintaining 20ATM water resistance. The watch case measures 10.6mm in height (12.7mm with crystal) and has a case weight of 70.6 grams. The entire case is also rounded and ergonomic so it can be worn comfortably during activities like surfing or diving.

This watch comes in a range of interchangeable strap options, and they are designed to fit wrists ranging from 6.5" to 8.5" in diameter - though we do have specialty straps available for those with wrists outside of this range.
