Tissot PRX 38mm Unisex Watch Grey

Ref. T1378074406100

The PRX traces back to a 1970s Tissot design shaped by Gérald Genta — the same hand behind the Royal Oak and the Nautilus — and the modern revival launched in 2021 has steadily expanded the line ever since. This 2025 titanium variant introduces both a new case size and a new material simultaneously, and the combination is not incidental: at 84 grams, it is meaningfully lighter than the stainless steel 40mm that preceded it, while the smaller footprint addresses a criticism that followed the original revival — that the 40mm wore too large over time without the 35mm feeling substantial enough. The integrated bracelet and fixed end links mean the watch reads larger on the wrist than 38mm implies, which is worth knowing before trying it on. The anthracite waffle dial sits against brushed titanium across both case and bracelet, building a coherent grey palette that the rose-tone hands interrupt — a point of genuine division among those who have worn it, given how well the rest of the watch holds together tonally. The movement underneath is built on the ETA 2824 platform with a Nivachron balance wheel, which resists both magnetic interference and temperature fluctuation, and an 80-hour reserve that makes weekly-winding habits unnecessary.
