Footnotes

The Movado "Polyplan" was launched in 1912 and made in both 18ct, 14ct gold and silver cases, with or without a seconds hand. At the time it was such an expensive watch that apparently only around 1,500 examples were produced.

The plate of the "Polyplan 400" calibre movement is angled at both ends to fit into the curved case with the compensation balance placed under the dial. This placement allowed the use of a larger balance resulting in a more accurate watch. The horizontal section of the plate contains the gear train and barrel, while the setting wheel, stem and crown are located in the upper angled part. Furthermore the "Polyplan" features a unique regulator arm which can be reached from the back so that the movement does not need to be removed from the case for adjusting.
