A. Lange & Söhne Langematik Perpetual in white gold
Lange’s first self-winding wristwatch with a perpetual calendar and an outsize dateis being presented with white-gold case and black dial.
The Langematik Perpetual was the world’s first wristwatch with a self-winding movement to incorporate a perpetual calendar with an outsize date. The perpetual calendar displays the date, the day of the week, and the month; it recognises the different number of days in each month and even the leap years. Once correctly set, the date display needs only to be corrected by one day every hundred years. The moon-phase display is a paragon of precision: it deviates from the true position of the moon by merely one day every 122.6 years, assuming the watch runs without interruption.
The solid-silver dial delivers an abundance of information at a single glance. The luminous hands and the rhodiumed-gold appliques clearly stand out against the dark background. A black crocodile strap and a white-gold prong buckle take the theme of vivid contrasts a step further.
The heart of the Langematik Perpetual is the proven self-winding SAX-0-MAT calibre with the patented Zero-Reset mechanism. When the crown is pulled, the seconds hand jumps to the zero position, thus simplifying the synchronisation of the watch.
The bidirectionally winding rotor in 21-carat gold with a platinum centrifugal mass builds up the maximum power reserve of 46 hours after only a short time on the wrist.
Numerous details of the meticulously finished movement can be admired through the sapphire-crystal caseback. It reveals the three-quarter plate made of untreated German silver, the classic screw balance, and the hand-engraved balance cock with the whiplash precision index adjuster.
The exclusive timepiece will be presented for the first time on 23 September 2014, when the first Lange boutique in Moscow is inaugurated.
