The countdown chronograph is the first of the ceramic 500m Chronograph models. The Countdown function, or otherwise known us the “Regatta” function, has been seen previously in other TAG Heuer watches, but shows a slight variation with this watch. Unlike previous chronographs, this watch introduces the “5-segment” display window seen in previous models of the brand. The design is similar to the 1982 original Aquaracer watch, which is when Jack Heuer launched the Heuer 2000 series. The first watch by Heuer sold that featured the “Regatta” function was the Aquastar Regate, which was first made available in the 1960s. In the 1970s, Heuer released Autavia-based Heuer Regatta. The “Regatta” or Countdown function is designed with the idea of yacht racing in mind. It splits time across 5 windows that each show 1 minute.
The Aquaracer 500m has case similar to the Aquaracer 300m series, except for a thicker case back and bezel. The bezel features over-sized numerals which are there more fore function than aesthetics. The case measures 43 millimeters in diameter. Many of the components of the Aquaracer have been made to ensure water resistance to a greater depth. This case is water resistant to 500 metes or 1660 feet. This round case is made of stainless steel and has brushed and polished finish. Inside this case is Swiss made movement that powers the watch. It is a self winding, automatic caliber. Other features of this watch include a ceramic bezel and a helium-escape valve.
The black dial of this Aquaracer 500m Calibre 72 countdown chronograph is quite attractive. The horizontal streaks on the dial nicely contrast the circular pattern of the two counters. The two counters are located opposite each other on the three and nine o’clock positions. The date window is located below the 12 o’clock position with the TAG Heuer logo located above the six o’clock position. Flashes of blue can also be seen in this dial creating another visual contrast when looking at the watch face.
