The Nomos Tetra (450), TAG Heuer Monaco (CAW2111), and Cartier Santos (W20073X8) are all square watches at different price points. Fun fact! The Cartier sports an “industrial look” with exposed screws, which pays tribute to the very first Cartier men’s watch. In 1904 Louis Carter was requested to make a timepiece by his friend Alberto Santos-Dumont to wear while flying a plane. This was just a year after the Wright brothers succeeded in their first powered flight. Back then planes required both hands to operate, and so looking at a pocket watch was not an option. In present day, the screws are a decorative element and a reminder that a watch is a tool and a machine on the wrist, not just a style or status symbol.
