The Aquaracer is Tag Heuer’s premier diving watch. The luminous hands allow time to be read underwater or in low light situations with ease. The screw down crown gives the watch a superb water resistance and the rotating bezel allows divers to keep track of their oxygen via timing. The Calibre 5 movement allows for fast date correction and a stop second time correction. The Calibre 7 GMT allows this watch to keep accurate time of two different time zones.
