This Universal Genève Compur (signed “Universal Watch Genève”) is a very early example from the early 1930s. In addition, the “UW” in a circle in the center of the dial indicates the early logo the company for a relatively short period until 1937 which adds to the rarity of this piece.
An interesting movement construction with the use of two column wheels for the chronograph function. The first column wheel is responsible for the chronograph button at the two o’clock position. It acts like a single-button chronograph with a similar function, which was often seen in a pocket watch chronograph, starting, stopping, and resetting the chronograph hand back to zero. The second column wheel, which is on the underside of the dial and linked to the chronograph button at four o’clock, allows the chronograph hand to restart and stop in between without resetting back to zero.
