Easily the equal of more expensive brands
Color: Black on Black Rubber
Interesting black dial and beautifully finished solid black PVD case. 39 mm perfect for my 7.25 inch wrist. Keeps time within +4 sec/day even though not COSC certified. Easily the equal of watches costing 2-4 times more like Breitling or Tag Heuer.

Beautiful watch
Got the PRX before this one and it felt small for my hands. Bought this one and it is a perfect dress watch. The band in PRX was better than this one though.
