Here is a 1930’s 24×40.5mm. gold plated and very uncommom, important (Historically) automatic winding MARS WIG-WAG. Automatic wristwatches were introduced in 1929 by Harwood. Many of the mechanisms from the early 1930s; such as those produced by Rolls, Wig-Wag, Autowrist and Wyler were among the first in the step towards the “ideal” automatic winding movement. The first automatic watches had their limitations, but the Wig-Wag seemed to work smoothly and functioned somewhat reliably over the years. This watch retains its ALL ORIGINAL dial with raised gold coloured markers and original blued steel hands. The (recently cleaned) Mars movement slides on rails up and down and is functioning perfectly. The condition of this watch is simply STELLAR. The Wig-Wag is a larger than average rectangular watch and looks very attractive on the wrist. This is an important watch to add to any collection.
