The Raketa “Sonar” model continues this tradition. It is a submariner’s watch by design and functionality:

• Its hands are inspired by the design of the hands in Soviet submarines’ control panels;
• These hands are powered by a Raketa 24 hour automatic movement (Raketa 2624А calibre) that allows submariners to distinguish day from night during their long underwater missions;
• The dial and hands are luminescent to allow submariners to read the time in the dark;
• 6 lines (in red and blue colours) divide the perimeter of the dial into 6 quarters (4 hours each) allowing each crewmember to keep count of his watches/shifts in the submarine;
• The automatic movement has a bi-directional rotor which doubles the winding-up efficiency of the watch (which is particularly useful in the cramped conditions of the submarine).

The back of the watch reveals the beautifully decorated 24-hour automatic movement which is entirely produced by the Raketa Watch Factory in Saint-Petersburg.
