The Lederer Triple Certified Observatory Chronometer is an ultra-rare, limited-edition timepiece (only 8 pieces worldwide) that sets a new standard in precision by earning certifications from four observatories: COSC, Besançon, Glashütte, and Geneva. Powered by the innovative Caliber 9012 manual movement, it features dual gear trains, constant-force mechanisms, and achieves an astonishing accuracy of just +0.18 seconds per day.
Housed in a 44mm 904L stainless steel case with a sterling silver dial and blued hands, it honors its observatory legacy with coordinate engravings and a compass rose on the case back. This chronometer is a celebration of horological excellence, blending technical mastery with refined, navigation-inspired design.
