Tissot PRX Chronograph - P 475 - Quartz - 1990s - 40mm Tissot PRX Chronograph, caliber reference P 475, in a 40mm two-tone case with gold-plated bezel and accents. Quartz chronograph movement, sapphire crystal, "SWISS-T" tritium marking dating the example to the pre-1998 production. The PRX line dates to 1978 and is the original Tissot integrated-bracelet sport-dress design that today's 2021 PRX revival reinterprets. This P 475 chronograph configuration belongs to the late 1980s / early 1990s generation that brought a Swiss quartz chronograph movement and a sapphire crystal into the line, paired with a textured black clous de Paris dial and a tachymetre outer scale. The design has the same Genta-era octagonal bezel and integrated bracelet vocabulary now driving the modern PRX market — collectors of the new line are increasingly looking back to find originals from this era. - Movement: Quartz chronograph, caliber P 475 (ETA-based) - Functions: Hours, minutes, sub-seconds at 6 o'clock with date window, 30-minute counter at 9, 12-hour counter at 3 - Case: Stainless steel with gold-plated bezel and accent links, 40mm, ~10mm thick - Dial: Black clous de Paris texture with applied indices and gold-tone hands - Crystal: Sapphire - Bracelet: Original Tissot two-tone integrated bracelet with signed deployant clasp, ref. P475/152 S - Water resistance: 100m as marked (untested for current vintage seal) - Year/era: late 1980s / early 1990s (Swiss-T tritium marking) This example is in good condition. The black clous de Paris dial is unblemished with sharp printing and intact applied indices. The sapphire crystal is clear with some light scratches. The case retains its original brushed finish on the steel surfaces. The gold-plated bezel shows visible plating wear and surface marks on the upper facets — typical for pre-1998 plated bezels worn daily. Original signed bracelet is intact with normal use marks, deployant clasp functions correctly. Quartz movement runs to spec; chronograph functions reset cleanly. The vintage PRX configuration with the original P 475 movement and black clous de Paris dial is increasingly hard to find. From a private collection. No box or papers.
