Description
The Sommerso Ceramic adds a two-tone green and black ceramic bezel to U-Boat’s 300-meter dive watch. The layered dial echoes those colors, with white luminous numerals and a visible ruby adding depth.
A Swiss Sellita automatic movement, a satin-finished 46 mm steel case and the brand’s left-side crown protector make it a capable diver with a refined, contemporary look.
