The PRX is available in both automatic and quartz movements. The automatic movement is the Powermatic 80, which is Tissot's most important movement, and will continue to run for approximately 80 hours when the mainspring is fully charged. A normal automatic movement would not last two full days, but the Powermatic 80 has an 80-hour limit, so even if you take it off on Friday night and put it back on Monday morning, the watch will still be running. A distinctive feature of the watch is the dial, which resembles the cobblestones of Paris.

Quartz watches have clean, unadorned dials and are available in a wide range of sizes and colors, giving you a wide range of options for pair watches.
