Tissot’s PRX Powermatic 80 fades blue into black

Tissot has given the 40mm PRX Powermatic 80 a blue-gradient dial that darkens toward the perimeter, a treatment that sharpens the contrast between the applied markers and the collection’s familiar waffle texture. Reference T137.407.11.041.03 is listed as a US exclusive and keeps the integrated 316L steel case and quick-release bracelet. The case is 10.93mm thick, protected by sapphire crystal and rated to 100 metres.

Inside is Tissot’s Powermatic 80 automatic movement, offering up to 80 hours of reserve and a Nivachron balance spring. A date aperture sits at three o’clock, while the transparent back reveals the movement. At $850 on Tissot’s US site, this is a colour-led update rather than a mechanical rethink—and a notably versatile one, shifting from bright blue to near-black as the light changes.
