Description

Before the Chistopol movement factory launched the still currently produced movement series of the caliber 2414 and relatives, they produced movement with a diameter of 22mm, such as the caliber 2214 shown here. The specimen shown here still got the old image mark.

This movement is special due to its unusual structure and of course of its gloden screw balance, which is even connected to a breguet-type hairspring with (short) regulator arm and runs in two inhouse shock protections.

The construction with its decentral minute wheel is unusual, too, but it is already a very modern one. This decentral wheel allowes a signficantly larger balance wheel which increased the precision. Since the center second hand is driven indirectly, we have the unusual situation of having five gears instead of the usual three or four.

What you also can see is, that the edges of the bridges and cocks are angled, so that this movement looks very nice, even without decoration stripes.

On the dial side, you also see pretty unusual things: The reduction wheel which drives hour and minute hand is kept in position by a spring; there's no real bearing. The advantage of that mechanism is, that the hour wheel is held in position by friction and thus jumping of the hour hand is avoided.

The rest of the dial side shows a familiar high quality and there's of course a yoke winding mechanism.
