The A. Lange & Sohne 1815 40mm watch. Model reference: 233.032. This is the purists model of the iconic 1815 style in rose gold. The 1815 model inspired by the founder Ferdinand A. Lange (and named after his birth year), offers a traditional take on Lange’s heritage watchmaking style. Exhibiting an aesthetic that is undeniably Lange, it features a railway-track minute scale around the outer edge of the dial. Symmetrical to this at 6 o’clock, a subsidiary dial displays the running seconds. In keeping with this classic styling, the dial further features large Arabic numerals and faceted blued-steel hands. The dial is also tiered, with the centre-portion slightly counter-sunk and the seconds sub-dial fractionally more so, adding subtle depth to the overall appearance. This watch features the L051.1 mechanical manual winding movement with an approximate 55-hour power reserve when fully wound. The movement is comprised of 188 components, of which 23 are jewels and five screwed gold chatons. Its rounded 40mm case is made of polished rose gold with brushed finished edges and a see-through back. A hand-stitched, blue crocodile strap with an engraved, rose gold ardillon buckle. The watch comes in original packaging, with a set of documents.
