Impressive Case Size.
Easily Interchangeable Straps which can be changed in seconds by the means of a quick-release button on the back of the case. The watch is supplied with an additional Black Rubber Strap.
Water Resistance - using the revolutionary new patented design. Although the crown & pushers are not "screw down" they are equipped with an external butterfly collar that turns a 1/2 turn clock-wise & counter clock-wise (independently of the crown & pushers), each collar has red & white enamel indicating arrows. White arrow indicates the crown is secure/water resistant, Red Arrow indicates the crown is non-secure/non-water resistant. When the collar is in the secure position it compresses a gasket that ensures water resistance.
The completely assembled watch undergoes a rigorous 1000 hours test before the watch ships from the factory!
