The Aquamatic IV Two-Tone is the latest evolution of the flagship dive watch, combining serious dive-watch performance with a refined steel-and-gold finish.
At its core is the Japanese Miyota 9015 Nickel 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.
The distinctive two-tone construction gives the Aquamatic IV a more elevated look without compromising its tool-watch capability. This fourth-generation Aquamatic features 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 smooth and precise.
When the lights go down, the dial lights up thanks to Super-LumiNova®, delivering brilliant nighttime visibility in all conditions.
