The Tissot PRX Automatic Chronograph takes the angular charm of the 1978 PRX and adds the most enthusiast-friendly complication of all. This version, with a white dial and contrasting black subdials, is the classic panda layout that recalls the motorsport chronographs of the 1970s.

The heart of the watch is the Valjoux A05.H31, a Swiss automatic chronograph movement with a long power reserve of around 60 hours, a big step up from older chronograph calibers. It drives three counters for timing up to 12 hours, a central chronograph seconds hand and a date, and you can admire it through the see-through caseback. The panda dial makes the counters pop, so readings are fast and the overall look is sporty and graphic.

At 42mm wide and 14.54mm thick, this is a substantial PRX with real wrist presence. It is the right choice for someone who wants a mechanical chronograph with heritage styling and a satin-finished integrated bracelet.
