The Tissot PRX has become one of the most familiar names in accessible integrated-bracelet watchmaking, largely because the collection refuses to sit still.
Its latest addition brings a white mother-of-pearl dial to the 40mm PRX Powermatic 80, giving the full-size automatic model a softer, more reflective character without changing the formula that made it work.
It’s a small update on paper, but an interesting one in practice, especially for a watch that trades so heavily on dial texture, case geometry and everyday wearability.

At a glance
- Tissot has added a white mother-of-pearl dial to the 40mm PRX Powermatic 80.
- The dial keeps the PRX’s waffle-style tapisserie pattern, applied markers, faceted hands and framed date at 3 o’clock.
- The model joins the permanent collection with pricing set at EUR 825, CHF 725 and USD 850.
Mother-of-pearl reaches the full-size PRX
Mother-of-pearl has already appeared in the smaller PRX line, but its arrival in the 40mm automatic case gives the material a different presence.
Rather than leaning into jewellery-watch territory, Tissot has kept the dial architecture recognisably PRX.
The white mother-of-pearl surface is worked with the collection’s familiar tapisserie-style pattern, so the iridescence sits beneath a graphic texture rather than overwhelming the watch.

That matters because the PRX is a design-led sports watch at heart, with sharp surfaces, an integrated bracelet and a relatively slim profile.
Applied metallic hour markers and faceted hands with Super-LumiNova maintain the practical, modern feel, while the date window at 3 o’clock is framed in metal for a cleaner finish.
The familiar steel case and integrated bracelet remain
The rest of the watch follows the established 40mm PRX Powermatic 80 layout.

The stainless steel case measures 40mm across and 10.9mm thick, with a 44mm lug-to-lug measurement before the first bracelet link.
That puts it in the larger PRX camp, but still in a size range many buyers will recognise as a contemporary daily watch.
The case combines brushed surfaces with polished accents, while the sapphire crystal, exhibition caseback and 100 metres of water resistance help keep the package practical.

The integrated stainless steel bracelet uses a triple-folding clasp with safety push-buttons and an easy-change system.
Tissot also offers compatible leather and rubber straps separately, allowing the watch to shift away from the full-steel look when desired.
The Powermatic 80 keeps the value argument strong
Inside is the Tissot Powermatic 80 automatic movement, a modernised calibre derived from the ETA 2824-2 architecture.

Its calling card is an 80-hour power reserve, which gives it a clear everyday advantage over many conventional automatic movements in this price range.
The movement also uses a Nivachron antimagnetic hairspring and runs at 21,600 vibrations per hour.
For buyers drawn to the PRX for its balance of design, mechanics and price, the mother-of-pearl dial adds visual variation without turning the watch into a different proposition.

The PRX line is already crowded, but this version earns its place by making mother-of-pearl feel less precious and more wearable.
For someone who likes the 40mm PRX silhouette but wants more light play than a standard metal dial can offer, it’s one of the more distinctive regular-production choices in the range.
