Russian Time

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.

The calibre K.01-7 of the “Russian Time” watch was developed by Konstantin Chaykin. The movement, which is equipped with an all-Russia time indication, was made entirely at the Konstantin Chaykin manufactory and based on a three-quarter plate construction. The calibre is made to the standards of haute horlogerie, using classical techniques in the finishing of its components: stripe grinding

In the upper part of the “Russia Time” watch dial there is a standard 24-hour time zone scale running along the names of Russian cities, while at the bottom a similar scale slowly moves under a schematic, yet still relatively detailed, map of the country, spread over eleven time zones. At the same time, daytime hours from 07:00 to 18:00 are shown on the scale with a light silver background, and night-time hours from 19:00 to 06:00 are shown on a black background.
