TAG Heuer has just unveiled its latest Aquaracer, the 500m Calibre 72. The first of the ceramic 500M Chronographs, the watch features a ceramic bezel on top of the steel case. This watch also marks the return of the “5-segment” display for the countdown timer, last seen on Heuer Regatta models from the 1970′s. The watch is water resistant down to 500 meters and is available with a rubber strap which will play well with water as well as the traditional stainless steel bracelet. No word on pricing yet but look for this to be available at official TAG Heuer boutiques next year.
