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 iconic 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.
