Lange revised the 1815 Chronograph for SIHH 2010, and the update wasn't cosmetic. The new caliber, L951.5, added a flyback function, letting the stopwatch reset and restart in one motion, and nearly doubled the power reserve to 60 hours from the first generation's 36. Ref 402.026 carries that movement in white gold, with a solid silver dial, painted Arabic numerals, and a 30-minute counter.
