Product Description

The A. Lange & Sohne 1815 Chronograph 39.5mm watch. Model reference: 402.026. An ideal everyday companion, the timepiece presents a minimal range of needed functions that makes it a perfect and laconic choice for an accessory. Its rounded 39.5mm case of 10.8mm thickness is made of polished 18K white gold with brushed finished edges and a see-through back. The solid silver dial has painted black minute track and hour markers presented by Arabic Numerals. The minute hand moves in 1 minute increments to read the timing function more accurate. At the 8 o’clock position, there is a smaller seconds sub-dial with a stop-seconds mechanism. The chronograph sub-dial is located at the 4 o’clock with the correction button at the same position. It features flyback function to allow restarting for continuous timing without having to reset it manually. All hands are of blued steel. The L951.5 mechanical movement is wound manually and consists of 306 individual parts. It contains 34 jewels and features 60-hour power reserve. The uniqueness of the iconic watch is enhanced by a balance-cock that is hand-engraved for every timepiece. The strap is made of black alligator leather and fitted with a tang buckle. The model is 30m water resistant. The watch comes in original packaging, with a set of documents and 2 years warranty. At Watches of Mayfair, we offer new authentic watches at the best prices.
