The Aquatimer Automatic 2000, a new, ruggedly built diver?s watch in the professional category, has a 42 mm diameter case. It is available exclusively in titanium with a titanium bracelet or a rubber strap. Every single watch is tested for pressure resistance to 200 atm or 2000 m below the surface. Like all Aquatimer Automatic models, it is instantly recognized by its two large, easy-to-operate crowns positioned off-centre on the edge of the case, where they will not disturb the diver underwater. The upper crown, which screws in, is used to adjust the movement and hands. To facilitate use during dives, the lower one does not screw in and has a complex, self-sealing design. It has several security features and is used to adjust the unidirectional rotating bezel inside the case via a sophisticated system of gears. Technology from professionals for professionals.
