Aquaracer 500M Automatic Chronograph is a dive watch by TAG Heuer.

In the spring of 2010 TAG Heuer presented the chronograph version of the model Aquaracer 500M Calibre 5 from the dive watch series Aquaracer (launched October 2010). The watch is, as the name implies, waterproof up to a depth of 50 atm.

The round, generously sized case (44 mm) is made of polished and satin-finished stainless steel. The uni-directional rotating bezel in satin-finished stainless steel has a black soft-touch coating and polished pushbuttons with lateral gripping grooves for ease of use with diving gloves. At 10 o'clock an automatic Helium escape valve is placed. This one-way valve triggers when the difference between the inner and outer pressure conditions reach a critical level.

The three totalisers on the black, vertically striped dial show the hours (at 6 h), the minutes (at 12 h) and the seconds (at 9 h) in chronograph mode.

The watchband can be chosen between a black rubber band and a three-rowed bracelet in satin-finished stainless steel with polished edges and center links.
