A. Lange & Söhne presents new blue dial editions of the Langematik Perpetual watch.
Introduced in 2001, the LANGEMATIK PERPETUAL by A. Lange & Söhne was the first mechanical wristwatch to combine a perpetual calendar with the Lange outsize date. It differs from other calendar timepieces with small but subtle features such as the ZERO-RESET mechanism and a main corrector for simultaneously advancing all calendar displays.
On the occasion of its 20th birthday, the prestigious German watch manufacture presents new editions of this iconic watch in white gold and pink gold, both combined with a blue dial, each in a 50-watch limited edition.
The blue dials of both new versions of the LANGEMATIK PERPETUAL are crafted from solid silver. The applied Roman numerals, underlaid with an embossed groove structure, prominently stand out against the dark background.
On the white-gold model, they are made of rhodiumed gold – just like the hands, appliques and lunar disc – and of pink gold on the pink-gold version. The hands for the hours, minutes, days of the week and month are luminous, as are the hour markers along the minute scale.
The design of the dial complies with the principle of information hierarchy, assuring the best and most intuitive legibility of the calendar displays. As the most important information element, the outsize date is prominently positioned.
The subsidiary dial on the left shows the day of the week; the one on the right displays the month. The perpetual calendar takes into account the different durations of the months in a four-year cycle, including those of the leap years.
Once the watch is correctly set, a manual adjustment of the date is not needed until the year 2100. The moon-phase display at 6 o’clock, paired with the subsidiary seconds dial, is also a long-term indication; it only requires a correction of one day every 122.6 years. All calendar displays can be advanced collectively with a (recessed) main corrector at 10 o’clock. They can also be set separately.
The self-winding L922.1 Sax-0-Mat calibre features the ZERO-RESET mechanism developed by Lange. When the crown is pulled, the balance wheel stops and the seconds hand jumps to the zero position. This simplifies and speeds up time setting.
The bidirectionally winding rotor ensures that the maximum power reserve of 46 hours is attained within just a short time on the wrist. Integrated in the three-quarter plate, it consists of 21-carat gold with a centrifugal mass in platinum. This makes the escapement with hand-engraved balance cock and classic whiplash precision index adjuster readily visible.
Thanks to a movement height of merely 5.7 millimetres, the watch has a very slender silhouette. The case has a diameter of 38.5 millimetres and a height of just 10.2 millimetres.
A dark-blue leather strap with a prong buckle in white gold or pink gold complements the harmony of the timepiece.
