Tissot PRX Automatic Chronograph 42mm Mens Watch

Ref. T1374271109100

The PRX first appeared in 1978 as an integrated-bracelet sports watch, went quiet for decades, and came back into production as a full family. This 42mm chronograph, introduced in 2024, sits at the top of that family — the only variant that combines the larger case with a mechanical chronograph, and the only one in this particular khaki green. The waffle-textured dial graduates from deep at the edge to lighter at the centre, which gives the three sub-dials — seconds, 30-minute and 12-hour counters arranged at 3, 6 and 9 — something to sit against. It reads differently in flat light than in direct light, the texture catching and releasing as the angle changes. On the wrist the integrated bracelet does the work it was designed to do, pulling the case flush against the wrist and distributing 184g in a way that registers as substantial rather than heavy. The 14.5mm case height is an honest consequence of fitting a full automatic chronograph movement inside a case this slim in profile; it is noticeable, though no reviewer has found it a problem in practice. The A05.H31 at the heart of this is the Valjoux column-wheel movement with a Nivachron balance spring, visible through the exhibition caseback. Nivachron is a nickel-phosphorus alloy that resists magnetic fields and temperature variation better than conventional steel — the kind of specification that matters more after a few years of daily wear than it does on the day of purchase.
