The Calibre 360 Chronograph concept wristwatch was introduced by TAG Heuer at the Baselworld 2005 show. It was described as the world's most accurate wrist chronograph - measuring and displaying in 1/100th of a second divisions. That's 10 times faster than the previous best for a mechanical chronograph.

The Calibre 360 is capable of this impressive accuracy because the chronograph is not simply a "module" added on to the main watch. It is an entirely separate movement with a high frequency balance wheel operating at 360,000 beats per hour.

The 2005 Calibre 360 formed the basis of the limited edition Carrera Calibre 360 Rose Gold.

In February 2006, TAG Heuer received the prestigious Red Dot Product Design Award for the Calibre 360.

Linear Second

At Baselworld 2006, TAG Heuer introduced the new Calibre 360 LS. The "LS" stands for "Linear Second".

The 360 LS design is inspired by the Monaco V4 and features the 1/100th second chronograph. Amongst the other features is the "Linear Second" indicator which gives the watch its name. This is embedded at the 3 o'clock position.
