Vostok Amphibian Military Russian Watch / KGB / Moscow / 200 m / AUTO #420457

The automatic watch is built with an oscillating metal weight, or rotor, that tracks movement. The oscillating rotor is attached to gears inside the watch that are in turn attached to the mainspring. When the rotor moves, it moves the gears which, in turn, winds the mainspring. This stores energy in the mainspring so that the watch continues ticking. If the watch is not being moved in regular, everyday motion, the mainspring’s energy winds down. If you wear your watch and keep your arm in regular movement, this should be enough to keep the rotor moving and winding up the mainspring. This doesn’t mean, however, that your arm needs to be in constant motion. Automatic watches are built to respond to average, everyday movement in order to keep them working.

Unscrew the winding head and pull it out to position 3. You will hear and feel a click. Turn the winding head counter-clockwise to set the correct time. After setting the time, screw the winding head into position 1.

 

Unscrew the winding head and pull it out to position 3. Set the correct date by turning the watch head counter-clockwise. When done, screw the winding head into position 1. There is a shortcut to changing the date. Unscrew the winding head and pull it out to position 3. Turn the winding head counter-clockwise until the hour hand reaches 12. Then reverse and turn it clockwise until the hour hand reaches 8. Reverse and go back to 12. This will move the date one position. Repeat as necessary. When done, screw the winding head into position 1. NOTE: Never go directly from position 3 (the time-setting position) to position 2 (the winding position). Instead screw down to position 1 then proceed to position 2. So after setting the time or date, screw down the cap then go to position 2 to wind it up.
