Manual Primus Automatic

Time setting

  1. Pull the crown out to the 2nd position.
  2. Turn crown clockwise to set the time. The crown can also be turned counterclockwise, but this may result in a defect of the movement!
  1. Push the crown back to the normal position.

Date setting

  1. Pull the crown out to the 1st position.
  2. Turn counterclockwise to set the date. We advise against setting the date in the period from 9:00 pm to 3:00 am. This can result in a defect of the movement.
  3. Push the crown back to the normal position. 

Automatic function

Every automatic watch is initially a hand-wound watch by its basic construction. Through an additional construction, a highly effective reduction gear takes over the process of winding. This gear is set in motion by an oscillating weight (rotor), thus tensioning the mainspring. The watch is thus charged by daily wear. The movements of the wearer set the rotor in motion, which tensions the watch. The efficiency of these movements varies. They may not be sufficient to achieve the full power reserve of 42 hours. Wearers of automatic watches therefore use watch winders. These are boxes for watch storage, which move the watch and thus charge it. Another possibility is the manual winding by hand described below. 

Manual winding

Since the Primus Automatic is an automatic watch, manual winding is usually not necessary. However, due to the low mass of the rotor, the efficiency varies from movement habit to movement habit. For some movements, the charging by the rotor in conjunction with the reduction gear is always only slightly greater than the simultaneous momentum of the gear train. To enjoy the full power reserve, it is therefore recommended to wind the movement by hand. And this is how it works:

  1. Turn the crown clockwise 12-14 times.
  2. You are already done. Tip: Now turn the watch to the back and enjoy the oscillating rotor and the gears visible through the sapphire crystal.

Today is the time

This is Vandaag

VANDAAG is Low German and means "today". And today is the beginning of the time for watches with a typical North German character: straightforward design, timeless lines, uncompromising quality - and that Made in Germany.
