The all-new ALPINA Extreme Diver Chronograph is a professional grade diving watch designed to deal with the most extreme conditions any professional diver could ever encounter, starting with water resistance to no less than 300 metres. The Extreme Diver 300 offers all necessary features that allow the professional divers and water sports enthusisists for a safe dive.
The black, polished, PVD coated, unidirectional, turning bezel, turns in just one direction: anti-clockwise. With this “fail-safe” feature the number of elapsed minutes can never be accidentally decreased, only increased. In addition, the 1 to 60 minutes markers on the bezel are luminous, as are the circular indexes which perfectly contrast against the black dial. The watch’s hands are also flared and luminous for maximum readability in low visibility conditions.
The sapphire crystal, see-through case back allows a glance of the inner workings of this automatic chronograph, a rare feature on professional diving watches with a 300 metres water resistance. The extra-wide 44 mm stainless steel case, the screw-in crown and case-back, the robust rubber strap with a secure folding buckle, the 46-hour power reserve, as well as the additional nylon diving suit strap, complete the professional features package.
The extremely reliable AL-725 automatic chronograph movement features a 12H-6H-chronograph counter layout with the 30-minutes counter at the 12 o’clock position and the 12 hours counter at the 6 o’clock position, in order to maximize the readability of the minute’s hand with respect to the 60 minutes diving bezel.
For the professional diver who prefers metal bracelets, the Extreme 300 Chronograph can also be fitted with classy “Milanese” metal mesh bracelet or the traditional Alpina 3 link sport metal bracelet. Each watch is presented in a uniquely designed gift box, which includes a model diving bottle and the additional nylon swimsuit strap.
