Mother-of-pearl joins the 40mm PRX Powermatic 80

Tissot has brought white mother-of-pearl to the full-size PRX Powermatic 80. Reference T137.407.11.111.00 keeps the collection’s 40mm stainless-steel architecture but replaces the usual geometric dial texture with a naturally iridescent surface, so each watch carries small variations in colour and pattern. Applied baton markers, a date at three o’clock and the integrated quick-release bracelet preserve the recognisable PRX layout.

The specifications remain deliberately familiar: sapphire crystal, 100-metre water resistance and the Powermatic 80 automatic calibre with a Nivachron balance spring and up to 80 hours of reserve. The movement is visible through the caseback. Tissot lists the watch at $850 in the United States, while Monochrome reported immediate availability at €825 when the reference was introduced in August 2026.
