Tissot PRX Powermatic 80 40mm Blue Gradient Dial T137.407.11.051.01

The PRX Powermatic 80 is built on Tissot's original 1978 tonneau case, the shape that relaunched the line as an integrated-bracelet sport watch. The dial runs a blue gradient, deepening from steel blue at the edge to near-black at center. Brushed steel forms the case and bracelet, under a sapphire crystal treated to cut glare. Inside is the automatic Powermatic 80, caliber C07.111, an 80-hour reserve visible through the caseback. This example is brand new, complete with its original box and papers. Among Tissot watches, this PRX is the one where the tonneau case gets noticed before the dial does.
