Lange says the name 1815 refers to the year the manufacture’s founder, Ferdinand Adolph Lange, was born. In yellow gold, this reference carries a dial that Lange describes as ivory-coloured argenté, made of solid silver.
The movement is calibre L051.1, manually wound, with 188 parts and a reserve of 55 hours; the balance beats at 21,600 semi-oscillations an hour (3.0 Hz). The case is 8.8 mm high, water resistant to 3 bar, with a sapphire glass case back. The strap is alligator leather, closed with a prong buckle in the case metal.
