Tissot PRX Powermatic 80 35mm Unisex Watch Green

Ref. T1372071109100

The PRX line traces back to a 1978 Tissot Seastar, revived in 2021 and expanded in 2023 to include this 35mm case — sized specifically for wrists that found the 40mm too commanding, and carrying the waffle-pattern dial that only appears on the automatic version of the family. The raised grid texture on the green dial is central to what the watch is. It gives the surface depth that shifts with the angle of light in a way a flat lacquer cannot, and it explains why buyers seeking the 35mm consistently specified the automatic over the quartz sibling. The integrated bracelet keeps the proportions flush to the wrist, though the first link does not fully articulate, which means the watch sits and wears slightly larger than 35mm implies — closer to a vintage 36mm in feel. The movement deserves mention beyond its 80-hour reserve. The Nivachron hairspring is a titanium alloy developed to resist the magnetic fields that standard springs accumulate from phones, laptops and airport security — a practical specification for a watch worn daily and not babied. The exhibition caseback lets you confirm the rotor is working; the sapphire is reserved for the dial side, where it matters more.
