A new manufacture calibre
The self-winding movement L021.3 is A . Lange & Söhne ’ s 67th manufacture calibre . It is based on the calibre L021.1 of the LANGE 1 DAYMATIC and has been endowed with a newly developed winding mechanism . Its technical features include a unidirectional winding rotor in 21-carat gold with an additional centrifugal mass in platinum , a power reserve of 50 hours , and a cam-poised balance that runs with a frequency of 21,600 semi-oscillations per hour .
Many of Lange ’ s quality hallmarks can be admired through the sapphirecrystal caseback : the plates and bridges made of untreated German silver and decorated with Glashütte ribbing , five gold chatons secured with thermally blued steel screws , and the hand-engraved balance cock with the superposed whiplash spring used for beat adjustments . As always , the parts of the movement , which is assembled twice , are manually finished to the strictest Lange standards . The materials , the architecture , and the artisanal finissage confirm that in terms of unique design and mechanical perfection , this watch is perpetual in every respect .
