The D4 Atlantic diver offers a unique value proposition as a daily wearer. From a distance, the proportions and finishing give it the look of a vintage mechanical collector piece (with 1960s era 38mm case sizing, and an anodized aluminum bezel). Yet if you look a bit closer, beneath its retro exterior, you’ll find a function forward 20ATM sport watch leveraging a perpetually powered solar-powered movement that provides both everyday accuracy and the appealing freedom to keep time off-grid.
