White gold and black dial: a classical combination of the watch industry, even for A. Lange & Sohne. It reminds you, without a doubt, about the magnificent Datograph Up/Down we reviewed a few weeks ago (and, to be true, that we really enjoyed). Now, the white gold –?black?dial combo is also available in the A. Lange & Sohne Langematik Perpetual, the perpetual calendar watch with automatic movement?of the Saxonian Manufacture.The A. Lange & Sohne Langematik Perpetual?comes with?ALS classical design, meaning a pure and refined round case polished on the top, brushed on the sides, with masculine and straight lugs. The Langematik Perpetual can easily be considered a dress-watch, with its reasonable 38.5mm x 10.2mm case, that now comes in white gold. Previously, the A. Lange & Sohne Langematik Perpetual was available in 18k pink gold and in solid platinum, both with a silver opaline dial. Ad - Scroll to continue with article The dial, a solid-silver plate, is quite specific on the Langematik Perpetual baucause of its indexes, showing applied Roman Numerals.?A. Lange & Sohne chose not to use them at 3, 4, 6, 8 and 9. Because of the sub-dials, it would have created partially cut indexes. The dial is showing several but practical indications, located in 4 sub-dials and an aperture:The A. Lange & Sohne?large date (with two separated discs) at 12The day of the week?and the day-night indicator at 9The month at 3The leap year in a small silver dial at 3, just under the daysThe Moon phase and the small seconds at 6All these indications can be adjusted by 4 recessed pushers in the case band (one main push piece for simultaneously advancing all calendar displays and 3 recessed corrector buttons for individually advancing the day, the month, and the moon phase). However, if the?Langematik Perpetual keeps running, it will need only one correction?every 100 years for the perpetual calendar and one correction every 122.6 years for the moon phase. And that is all due to the very nicely manufactured and complicated movement.The A. Lange & Sohne Langematik Perpetual?comes with a self-winding movement, build around a three-quarter rotor architecture, that preserves the ? bridge?style, dear to the german brand. As usual with?A. Lange & Sohne, it fits perfectly the case and comes with beautifully?executed?finishes (and as always, it’s assembled?twice – the reason why is explained in our review of the Datograph Up/Down). Alongside being a feast?for the eyes, the Sax-0-Mat?is also a technically advanced calibre. It features a subsidiary seconds with stop seconds and patented ZERO-RESET function (meaning that the seconds hands goes back to the zero position when pulling the crown), an integrated three-quarter rotor in 21-carat gold and centrifugal mass in platinum for a more efficient winding and 46 hours of power reserve. Of course, it is adjusted in 5 positions and comes with a balance cock engraved by hand and bridges and plates in untreated german silver. On the wrist, it is another gorgeous and complicated watch that fits perfectly an elegant man’s writs. The new black dial / white gold combination is certainly a bit more easy to wear with a casual outfit and then, a bit less rigid than a pink gold / silver dial edition.A Lange & Sohne new boutique in MoscowThe A. Lange & Sohne Langematik Perpetual?in white gold with black dial will be delivered on a black crocodile?strap and priced at 68.000Eur.
