Erwin Sattler is a family-owned high end precision clock manufacturer, today the only one of its kind in the world. Its founding dates back to 1903 when Heinrich Sattler patented a mantel clock with an integrated perpetual calendar. Some 60 years later, Erwin Sattler founded the company that is still in existence today, now owned and managed by his daughter, Stephanie Sattler-Rick, and her business partner Richard Müller. Most watch brands (certainly the ones that manufacture more than 100 units a year) can only dream of the depth of manufacturing and production independence that Sattler achieves. With the exception of very few non-mechanical parts (the glass used in the casing, for example), Erwin Sattler manufactures every single part of the clocks in-house at its factory in Munich’s suburbs. That means every plate, bridge, screw, hand, spring, dial, pendulum rod, weight, and case is crafted in the company’s own laboratories and workshops. With a team of about 30 master clockmakers, metallurgists, physicists, tool makers and others, the company has expanded its product portfolio over the years from ultra-high precision pendulum clocks that have no rival to highly complicated time machines, high-tech watch winders, wristwatches, and nautical instruments.
