Evolution of the wristwatch through key historical innovations

The history of the wristwatch is marked by several key innovations that transitioned the device from decorative jewelry to a reliable tool. Rolex founder Hans Wilsdorf focused on chronometric precision and durability, aiming to create a case tight enough to protect movements from dust, water, and temperature changes. In 1910, a Rolex wristwatch was certified for precision by the Swiss Official Watch Rating Centre, and in 1914, it received a “Class A” certificate from the Kew Observatory in Great Britain.

Other significant milestones in watchmaking include the Cartier Santos, which was designed for Brazilian aviator Alberto Santos-Dumont to allow for easier use during flight, helping to normalize wristwatches for men. Additionally, British watchmaker John Harwood is credited with building the first automatic wristwatch, the Harwood Automatic, which was produced in collaboration with Fortis in the mid-1920s.
