By TLex NauticFish of Germany have released a new Waterwall Chronograph for 2012. The new ETA-7750 powered diver has a water-resistance of 2000 meters, which is quite impressive for a mechanical chronograph. I believe the 2009 Waterwall Chrono had a water-resistance of just 500m.
NauticFish have tested and certified the water-tightness of the new Waterwall Chronographs in-house. Their high level of water-resistance has been achieved by a combination of technologies that NauticFish have taken from their existing MSC Series, which feature a 'multiplex-water-tightness system' that seals the winding crown and (in this case also) the chrono pushers, which are most vulnerable.
Because these watches are sealed so tightly there is no need for a helium release valve. Seiko make the same claim about their Marine Master Professional 1000m, which they say is also SAT Safe (safe for saturation diving). The MSC Series and new Chrono are also equipped with 5mm thick screwed Sapphire crystals and 120 click-type divers bezels.
The steel case of the Waterwall Chrono measures 45mm x 19.9mm. It is available with either a pearl-blasted or black PVD finish. It's a familiar sight, but one that combines the dial to create a very nice technical looking dive watch. The dial itself has 3D design with a wave patter and three recessed sub-dials.
The dial is available in either black or orange. The hands are with C3 SuperLuminova. The large white circular hour markers make use of a combination of phosphorescent pigments and ceramic, a relatively new Swiss technology where the luminous areas are actually cut to fit rather than painted on. Corum have a special version of the Deep Hull that uses the same technique
The Waterwall Chrono comes with a 24mm steel link bracelet with a quick-change-system (accessible from outside), so it is comfortable to switch between strap or bracelet at anytime. It is supplied in a waterproof and shock-resistant NauticFish Outdoor box along with some tools.
