When introduced in 1912, the Movado Polyplan was offered in 18k, 14k, and stainless steel cases. The unique case design resulted in the Polyplan 400 caliber movement, which is angled at both ends to fit tightly in the case. The movement is also noted for having the compensation balance under the dial. This configuration permitted the use of a larger balance wheel, which in turn increased the accuracy of the mechanism. Perhaps the most distinguishing feature of the Polyplan is the winding crown position, which is located at 12.
It is believed that only approximately 1,500 examples of this model were produced. Examples in 18k white gold are very rare and highly sought after by collectors.
