It's water resistant to 30 meters/100 feet, and it has a 46-hour power reserve at full wind. The 9.8mm thick case, dial, and movement are all signed. The automatic self-winding A. Lange & Sohne Caliber L085.1 SAX-0-MAT movement is Glashütte 3/4 plate in German silver, with fausses cotes embellishment. It's constructed with 43 jewels, a shock absorber mechanism, and a straight-line lever escapement. It includes a monometallic balance that's adjusted to 5 positions, a self-compensating flat balance spring, a swan neck micrometer regulator, and a 21K gold micro-rotor with a platinum segment. It includes a hand-engraved balance bridge, and the mechanism oscillates at a frequency of 21,600 vph (3 Hz). The Saxonia was originally Walter Lange’s manually wound, elegant homage to Saxony and his family’s lineal heritage. This watch honors the Saxony tradition of craftsmanship inspired by Augustus the Strong and the technical artistry of Court Clockmaker, Johann Gutkaes, mentor, father-in-law, and eventually the partner of Adolph Lange.
