  • I've had this watch since July 2015 and I have to say its fantastic. It is great on a number of strap combinations and the bracelet is very comfortable. The acrylic holds up to day to day wear very well and it does not yet require any polywatch to buff it up. The chronograph pushers function well and feel very responsive to the touch. If you are on fence I would not hesitate I would also recommend getting the bracelet.
