About this watch

The Doxa SUB 300 Aquamarine is a statement piece that combines performance and aesthetics for both diving enthusiasts and casual wearers. With its vibrant blue color and matte finish, this watch pops against the wrist, reminiscent of ocean depths. The tonneau shape is both unique and ergonomic, making it a comfortable fit. Crafted from stainless steel, this watch withstands pressures up to 300 meters. At the core is the ETA Caliber 2824-2 automatic movement, renowned for reliability and precision. The rotating bezel tracks elapsed time effortlessly, while luminous hands ensure visibility underwater. Durable sapphire glass and a robust case endure both elements and time.
