A. Lange & Sohne – Langematik Perpetual Black Dial
The Langematik Perpetual was Lange’s first self-twisting wristwatch with a perpetual calendar and an outsize date. Today A. Lange & Sohne announced another variant of this exceptional timepiece, part of the Saxonia collection, which combines a white-gold case with a profound black dial.
The perpetual calendar shows the date, the day of the week, the month, and recognizes the diverse number of days in each month and even the jump years. Once correctly set, the date show needs just to be corrected by one day at regular intervals. The moon-stage show is also amazingly accurate as it digresses from the genuine situation of the moon by simply one day each 122.6 years (accepting the watch runs without interference).
All showcases of the perpetual calendar can be switched separately or collectively. Collective change is performed with a push piece situated at the highest point of the case. More modest push pieces permit the day of the week, the month and the moon-stage show to be advanced independently.
The black, strong silver dial enhances the contrast with the iridescent hands and rhodiumed-gold appliques which clearly stand apart for excellent neatness.
The 38.5 mm classic white gold case houses oneself winding Sax-0-Mat caliber which can be appreciated through the sapphire crystal caseback with its typical three-quarter plate made of untreated German silver and the hand-engraved balance cock with the whiplash precision record agent.
Because of the protected Zero-Reset mechanism, when the crown is pulled, the seconds hand leaps to the zero situation to improve on the synchronization of the watch. The bidirectionally twisting rotor in 21-carat gold with a platinum centrifugal mass develops the greatest force hold of 46 hours after just a brief timeframe on the wrist.
The new A. Lange and Sohne Langematik Perpetual (ref. 310.026) will be introduced today during the initiation of the primary Lange shop in Moscow.
