Aquamatic IV
The Aquamatic IV is the latest evolution of our flagship dive watch, purpose-built with top-tier components and standout value.
At its core is the Japanese Miyota 9015 Gilt automatic movement, part of Miyota’s premium line, offering a smooth 28,800 BPH sweep, 42-hour power reserve, and 24 jewels. It’s a robust, reliable engine with luxury-level refinement.
This fourth-generation Aquamatic features a long list of upgrades: a scratch-resistant sapphire crystal with anti-reflective coating, an offset screw-down crown for 200M water resistance and all-day wrist comfort, and a 120-click unidirectional ceramic bezel that feels precise and reassuring.
When the lights go down, the dial lights up, thanks to SuperLuminova, delivering brilliant nighttime visibility in all conditions.
