For the “Russian Time” watch Konstantin Chaykin developed the K.01-7 calibre with manual winding, in which he abandoned the industry-standard time zone indicator construction with a discreet switching system, where the indicator is usually configured in one-hour intervals. Instead he decided to use interference fit which is traditionally used, for example, in the gear train that turns the timepiece's hands. This solution enabled the use of buttons to be avoided. For setting the time on the “Russia Time” watch, the crown is extended and rotated clockwise, allowing all the time indicators to move together in perfect synchronicity. If the crown is turned anti-clockwise, only the time zone indicator is altered.
