Sothis watch brand was founded by Wolfgang Steinkrüger in 1996 in Bielefeld, Germany. The first model produced by the brand is “SPIRIT OF MOON”; with a diameter of 39mm and 3 different face variations. In 1998 the “Spirit of the moon” won a prize in the “Goldene Unruh” competition in Basel.
The brand name Sothis is inspired by the Greek name of the Egyptian goddess Sopdet.
Initially, the movements, hands and all other parts of the Sothis watches were sourced from the established suppliers based in Switzerland. Each watch was assembled exclusively in the Bielefeld workshop. After a while, the company started to use watch parts made in Germany except movements and hands.
In December 2012, the brand was acquired by new owners after the demise of Wolfgang Steinkrüger in March 2012. In 2013, the new owners transferred the production to Switzerland.
Most Sothis watch self-winding movements can be wound properly by most watch winder boxes. Usually Sothis’ self-winding movements need to rotate 650 - 800 revolutions per day, and most of them can be wound clockwise. So please take some time and like to choose a cute clockwork that suits you and your watch.

If you could not find your watch model (or caliber) in this table, you may determine your Sothis watches. winding mode on a trial basis. You should select the combined winding mode (CW+CCW) and the minimal number of turns per day (TPD). Then place your watch into the gyro watch winder and check after a few days how accurate your watch shows the time. If it runs behind, it is necessary to increase the number of TPD by one step.
