Tissot Heritage 1973 with Blue Dial

In developing the Tissot Heritage Navigator Chrono Auto 1973, Tissot summoned a model from its archives. Dating back to 1973, the Navigator Chronographe was essential in connecting Tissot with motor-racing. The sportiness that is intrinsic to the Tissot Heritage Navigator Chrono Auto 1973 is evident at every level. At 46.6 mm high and 43 mm wide, this is a substantial instrument designed to be assertive. However, the choice of stainless steel for the case is an understated one. Indeed, the natural curves of the Tissot design envelop the arms. This is a comfortable, ergonomic piece, particularly thanks to the shortened horns which enable the strap to descend vertically toward the wrist. This effect is further accentuated by the domed transparent sapphire glass box which follows the same line as the curve of the case.

Another sport-inspired aspect of the Tissot Heritage Navigator Chrono Auto 1973 - a mechanical one - is the self-winding chronograph movement, the Valjoux A05.H31 calibre. While maintaining its 4 Hz frequency and therefore its full precision, it offers a 60-hour power reserve. This characteristic, rare among chronographs, makes it possible to leave the Tissot Navigator aside for two days and two nights. When strapping it again onto the wrist, it will still be on time, and still sufficiently wound to maintain its chronometric performance.
