Dark, refined, and built for depth - the Abyss bezel captures the transition between night and day with a gradient of black and deep blue. Finished with precision-engraved gold markers, it brings warmth and sophistication to the classic GMT design. Inspired by the quiet intensity of deep water and the glint of sunlight above, Abyss balances function with elegance, giving the Black Bay 58 a look that’s both commanding and composed. Crafted from anodized aluminum for lasting durability, it’s a bezel designed to perform as beautifully as it looks.
Fully reversible, the Abyss bezel allows you to return to your original bezel whenever desired - offering versatility with enduring style.
Wear it your way and bring a touch of refined depth to your watch.
