Russian Time. Krusenstern

The world time indicator on the case back is synchronised with Chaykin’s all-Russia dual time zone indicator. The construction looks mysterious, as at first glance it appears the two indicators are not connected at all. The sapphire disk allows the world time mechanism to be completely visible. Konstantin Chaykin is the recognised master of the “mysterious” watch, but he reveals the secret of this construction: “We placed a sapphire disk in the back of the movement, an idea just like in the “Levitas” watch. Via a pinion meshed with teeth around its edge, the rotation is transmitted through the movement from the upper disk of the time zone indicator, which is found on the opposite side of the dial.

The calibre K.01-7 WT of the “Russia Time. Krusenstern” watch was developed by Konstantin Chaykin. The movement, which is equipped with an all-Russia time indication with world time indicator on the case back, 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: striped and perlage; fine longitudinal, radial and circular grindings; manual chamfering, polishing; polished screw holes, pins and jewels; spherical polishing of the axel tips; engraving; and galvanized rhodium and gilded plating. Distinctive features of the movement are the gold branded regulator (a device developed by Konstantin Chaykin to fine tune the effective length of the spring).

The case and dial of the watch are exquisitely decorated by hand. The case, made of 18-carat rose gold, is artistically engraved and embossed along the lateral edge, with each side of the crown featuring carefully detailed images of the sloops-of-war “Neva” and “Nadezhda”, the two ships on which Russian sailors set out to circumnavigate the globe. On the opposite lateral edge from the crown a world map showing the expedition route has been engraved. The dial is also engraved, with a map of Russia painted in hot enamel – all eleven time zones are marked in colour on a schematic, yet still detailed, map.

Case dimensions: Diameter 44 mm, thickness 13,5 mm
