Notes
This Mortiz Grossmann PIECE UNIQUE represents the pinnacle of Glashütte’s horological mastery. A magnificent flying three-minute tourbillon rotates beneath the brown silver dial, showcasing centuries of German watchmaking tradition with modern innovation. The 18K white gold case houses a masterfully finished manual-winding movement , the CALIBER 103.0 in High Artistic Finish features a flying three-minute tourbillon with screw-secured driving wheel and distinctive V-shaped balance bridge. The innovative stop seconds mechanism uses a pivoting fine-hair brush at the balance wheel rim (patent pending). The proprietary Grossmann winding mechanism and pusher complement the ingenious second stop with a brush made of human hair to halt the balance with unprecedented delicacy and precision.
