PRX Powermatic 80 Black
or PRX Powermatic 80?

Identical watches apart from the dial. Black is the most versatile and understated PRX; blue shows off the waffle texture and adds colour without being loud. If you only own one watch, we lean black; if it joins a collection of dark dials, choose blue.

Before you order.

Black dials show less of the waffle texture than lighter colours. The integrated bracelet decides the fit, and Tissot publishes a 39.5 mm case length rather than an effective lug-to-lug.

The integrated bracelet shapes the fit. Tissot publishes case length, which is not a verified effective lug-to-lug measurement.
