A. Lange & Söhne 1815 Rattrapante Honey Gold Homage to F. A. Lange 425.05

It belongs to the Homage to F. A. Lange trilogy, three Honeygold models with the 1815 Thin and the Tourbograph Perpetual, made for the 175th anniversary of Saxon watchmaking: Ferdinand Adolph Lange opened his pocket-watch workshop in Glashütte on 7 December 1845. Honeygold is an 18k alloy developed for Lange and harder than other gold alloys. The calibre L101.2 runs the chronograph and its split-seconds hand, and the polished case is 12.6 mm thick under a sapphire crystal.

Its closest relatives are the 1815 Rattrapante Perpetual Calendar references (platinum 421.025, pink gold 421.032), which add a perpetual calendar and moon phase on the L101.1 in a 41.9 mm case 14.7 mm thick. From the same trilogy, the 1815 Thin Honeygold 239.050 is a time-only 38 mm watch with a white enamel dial, made in 175 pieces. For a chronograph without the split-seconds hand, the 1815 Chronograph references such as the 414.028 are 39.5 mm flybacks, 10.8 mm thick.
