The world is shrinking, and more people than ever need to stay in touch around the globe. Reactor's new Proton makes it easier than ever to know the time anywhere with a simple twist of the world time bezel. Simply set Proton to the local time wherever you are, turn the bezel so the city in your time zone aligns with the hour hand, and the local time in any other time zone can be read right off the bezel - it even has notations for regions that don't follow daylight savings! Plus, it's a great looking timepiece in a very wearable 45mm diameter case. Inside the Proton watch there is a very accurate Japanese quartz chronograph movement with a 60-minute stopwatch function, a 24-hour sub-dial and a date at 4:00. The screw-down crown is protected with tapered extensions on the side of the case. The chronograph pushers are screw-down. Make sure to screw them down if you are going swimming. There is a forged (screw-in) case back and the bracelet is secured to the case with solid screw bars (rather than push-pins). And, the radiant blue dial features SuperLuminova Illumination on the hands and hour markers to allow you to see the time in low light or dark conditions. The watch will come to you nestled inside Reactor's distinctive cylinder container. Features Movement: Japanese quartz chronograph (battery operated) Case: Stainless steel, 45mm x 14.5mm thick.
