When Tissot reintroduced its PRX line, the brand did more than revive a retro design: it gave it mechanical life. The Tissot PRX Powermatic 80 40 mm is the embodiment of that intention — retaining its 1970s flair while offering modern performance and finishing. This review walks through its design, movement, pros & tradeoffs, and why it continues to appeal to watch aficionados.
Heritage Meets Modernity
The PRX model draws direct lineage from Tissot’s 1978 “Seastar PRX,” a slender barrel-shaped steel watch with an integrated bracelet, bold facets, and simple time + date functionality. In relaunching the PRX with an automatic movement, Tissot honors that heritage while elevating the proposition for today’s market. The design retains its slim profile, sharp lines, and integrated bracelet while bringing in contemporary touches that blend tradition and ambition.
Case, Dimensions & Wearability
The PRX Powermatic 80 40 mm features a barrel-shaped case that measures 40 mm in diameter, with a thickness of around 10.8 mm and a lug-to-lug span close to 44 mm. These proportions allow it to sit comfortably on a wide variety of wrists—neither too small nor overwhelming. Thanks to its slim height and integration of the bracelet, it curves snugly around the wrist, offering both presence and ergonomic comfort.
Surface finishing is well executed: brushed top surfaces, mirror-polished bevels, and precise transitions give the watch an upscale feel. The raised bezel adds depth to the profile, and the sides include polished facets to elevate visual interest.
Water resistance is rated at 100 meters, and both front and back crystals are sapphire, ensuring durability and scratch resistance.
Dial & Bracelet
A defining feature of the mechanical PRX is its textured dial. Rather than the vertical brushing seen in quartz versions, this iteration sports a “waffle” or “tapisserie-style” embossing—branded by Tissot as a raised honeycomb pattern. It gives the dial more depth and character. Applied indices and hands with polished surfaces and luminous material ensure legibility in dim conditions. The date window sits neatly at 3 o’clock, framed modestly to integrate with the overall aesthetic.
The integrated bracelet continues the case’s lines seamlessly. Its links are brushed with polished accents, and it uses a concealed triple-folding clasp. While the bracelet is comfortable and flexible, the absence of micro-adjustment and reliance on pin adjustments for sizing are minor compromises, likely tied to its accessible pricing.
Movement & Performance
Under its case lies the Powermatic 80 (derived from the ETA C07 family), a core strength of this model. The movement offers a generous 80-hour power reserve, achieved by optimizing the gear train and mainspring. It also features a Nivachron hairspring, giving the movement better resistance to magnetic fields. While the lower-cost version uses 23 jewels, some components in the escapement are polymer-based; though not a critical flaw at this price point, it’s a detail worth noting for purists.
The movement operates at 3 Hz (21,600 vibrations/hour) and allows for smooth, consistent timekeeping. Through the sapphire caseback, you can observe the rotor and movement finishing in action—a pleasing touch for mechanical watch lovers.

It’s hard to fault the execution at this level, and for many, it represents one of the best value propositions in modern Swiss horology.
