The A. Lange & Söhne 1815 Tourbillon reference 730.079F is a 39.5 mm platinum dress watch housing a hand-wound tourbillon movement, representing one of the most technically and aesthetically refined complications in German haute horlogerie. The platinum case is matched by a platinum bezel and a hand-stitched leather strap, projecting understated, aristocratic elegance on the wrist.
Reference 730.079F stands apart through the rare combination of a full platinum case, platinum bezel, and the storied 1815 lineage — named in honor of Abraham-Louis Breguet's master pupil Ferdinand Adolph Lange's birth year — making it a serious collector's piece and a sound long-term investment. Contact Bizak & Co. today to inquire about availability, pricing, and authentication for this extraordinary timepiece.
