Harwood Engraved Automatic

Every now and then a watch comes along that doesn’t just tell time — it changes the course of watchmaking. The Harwood automatic wristwatch is one of those pieces. Invented by English watchmaker John Harwood and patented in 1924, it represents the world’s first mass-produced self-winding wristwatch. At a time when nearly every watch required daily winding, Harwood’s system introduced a new idea: let motion do the work. Produced in Switzerland in the late 1920s through collaborations with manufacturers such as Fortis and Anton Schild, Harwood watches housed an ingenious 'bumper' automatic movement. Inside, a weighted rotor swings back and forth like a see-saw, winding the mainspring as the wearer moves throughout the day — a concept that would become the foundation for nearly every automatic watch that followed. The design is just as fascinating. In keeping with Harwood’s crownless concept, there is no traditional winding crown. Instead, the fluted rotating bezel is used to set the hands. A small circular aperture above 6 o’clock acts as a running indicator, changing color to show whether the movement is operating or has stopped. This example features the classic late-1920s aesthetic: a cushion-shaped case, silver-toned dial with radium Arabic numerals, and a revolving 'reeded' bezel. Even better, the case bears period engraving, a reminder that watches like this were not only technological milestones but personal objects meant to be worn and remembered. Rare, historically important, and endlessly charming, the Harwood remains one of the most significant early chapters in the story of automatic watchmaking.
