The International Watch Company isnt your run of the mill luxury watchmaker. It was founded in 1868 by Boston entrepreneur Florentine Ariosto Jones who decided Swiss mastery along with American technology equates to elegant and utilitarian timepieces. Working with Johann Heinrich Moser of Switzerland, they created a family of superb dive watches known as the IWC Aquatimer. Sporting a distinct colored arc for the first quarter hour, it is also equipped with a bracelet quick-change system as well as an excellent luminescent coating on the underside for unrivaled legibility. The 42mm to 44mm IWC Aquatimer is crafted from steel, 18k rose gold, or titanium and features, depending on the model, hours, minutes, hacking seconds, day, date, and chronograph functions powered by an automatic movement. With a water resistance of 12 to 200 bar, the IWC Aquatimer is the ultimate tool for any serious diver.
