Zeno-Basel Pro Diver II

With an impressive diameter of 48 mm, the Pro Diver II will make waves in a big way. The diver’s watch, incorporating a self-winding ETA movement or a Ronda quartz caliber, is in a category of its own.

The rugged matt steel case frames a black dial with Superluminova-coated baton markers and hands to assure crisp legibility in any situation. For safety reasons, the bezel can only be rotated clockwise. This prevents inadvertent prolongations of the intended dive time. The Pro Diver II with a helium valve is an indispensable companion for professional divers.

The valve prevents the ingress of tiny helium atoms into the case and rules out an explosion of the anti-reflective sapphire crystal as a result of over-pressure. The diver’s watch persuasively combines superb functionality and advanced technology. The screw-down crown assures water resistance to 500 meters.

With its robust, stitched silicone strap and the double safety clasp, the Pro Diver II is a reliable companion in the underwater realm.
