Lot Essay
According to the Archives of Movado, the present watch was manufactured in the early 1940s.
The "Cronoplan" was introduced to the market in 1937, using the universal calibre 150 MN, and featuring an ingenious construction allowing long-term time recording (only hours and minutes) without time consuming calculations. Movado was granted Swiss patent no. 191277 on 12 November 1936 for a system consisting of two concentric rotatable bezels surrounding the crystal. The inner bezel is calibrated for the hours, the outer for the minutes. In order to time an event, the 0 of the inner bezel is placed above the hour hand and the 0 of the outer bezel above the minute hand. At the end of the recording, the elapsed time can be read directly from the numbers indicated by the two hands.
The Movado Cronoplan is described and illustrated in The Movado History by Fritz von Osterhausen, pp. 104, 108 and 110.
