    I have over the years collected a few examples of earliest self-winding wristwatches covering the developments of the first experimental phase from 1929 to 1935. I will be posting these watches over the next few weeks and I hope you will enjoy seeing them.

    THE HARWOOD AUTOMATIC - Hammer Winding

    The first "self-winding", or "automatic", wristwatch was the invention of a British watch repairer named John Harwood in 1923. The winding mass was a 'hammer' that was mounted on both sides of the movement but wound the watch only in one direction as it would 'swing'. Its impact was dampened by spring buffers. The back-and-forth motion of the hammer couples to a ratchet to automatically wind the mainspring. The first Harwood Automatic was first displayed at the Basel Fair in 1929.

      Very cool, almost looks like an earlier Rolex style with those arabic numerals.
