01TheOne - Boulder - Blue LED - SLS113B3BL - Both the Slim Square and the Slim Round were inspired by summer in Boulder Colorado. Colorado may not seem as hip, racy, or untamed as Samui or Kerala, but it is just as effective in bringing forth inner peace and happiness. In Boulder you feel beautiful landscapes of mountains, pines, and streams accompanied by a warm wind that just feels American. This got us thinking about the basics. We wanted the most basic shapes possible, and we thought of a square and a circle. The Slim Square is simple, sleek, and surprisingly elegant. It sits nicely and looks serene on the wrist. It should also be said that this watch is different. It takes up a lot of wrist real estate and it gets noticed. It tells the time in a binary format with LED lights. The strap is made of polyurethane. Quartz movement - 316l stainless steel case - Binary time - Water resistant to 165 feet (50 M) - Case diameter: 45 mm - Case Thickness: 6.6 mm
