Lot Essay
The Movado "Polyplan" was launched in 1912 and made in 18K and 14K gold and silver cases, with or without a second 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, the compensation balance is 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.
The model combining an Art Nouveau style dial with a very modernistic, slender case design was and still is much sought after by collectors.
The "Polyplan" model is described and illustrated in The Movado History by Fritz von Osterhausen, pp. 34-38 and in Armbanduhren - 100 Jahre Entwicklungsgeschichte by Kahlert, Mühe, Brunner, fifth edition, p. 43, pl. 62 and p. 224, pl. 432-436.
