The PRX has been a real winning timepiece for Tissot, the Gérald Genta inspired design from the 1970s is very popular. The Reference T137.407.11.091.00 with the dark green waffle [tapisserie] pattern dial with applied metallic markers is my choice. The narrow baton hands with Super-LumiNova makes for a pretty stylish dial.

The 40 mm brushed 316L stainless steel tonneau shaped case with polished accents is very 70s retro styled that seamlessly merges with the integrated stainless steel bracelet. There is no screw-down crown offering a 100 metre water resistance. A sapphire crystal and display caseback is less than 11 mm in height. The triple folding clasp with safety push-buttons ensures a neat bracelet, the bracelet is pretty thin.

The Powermatic 80 is an upgraded ETA 2824-2 automatic movement with Nivachron anti-magnetic hairspring and 23 jewels. The 80 hour power reserve is based on a larger barrel and 21,600 vibrations/hour frequency. The 3 Hz frequency affects accuracy, I am not sold on the larger power reserve with reduced accuracy, I appreciate this is the direction the watch industry is moving. I am in the minority here and accept that I am wrong, I know what the Powermatic 80 is and still choose the PRX as a very good watch for the price.
