Without astonishing hand-engravings on its interface and inner-parts, this limited edition of the brand’s iconic Lange 1 would be ‘just’ the masterpiece of the haute horology. This way, new A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar Handwerkskunst watch is also an exceptional piece of art. Produced in the series of just 15 pieces, this watch features three highly valuable classic complications – a perpetual calendar, a tourbillon and a moon-phase indicator, which classified it among highly complicated timepieces. Besides, it deserves the highest marks for its distinctive aesthetics and superb functionality.
The arrangement of the perpetual calendar feature is especially impressive. At the outer rim of the beautiful dial, there is a patented peripheral ring which indicates months in the conjunction with an arrow at the 6 o’clock position. Another elegantly designed display extends on both sides of the 9 o’clock position. It is the retrograde day of the week indicator, placed just below the prominent double date window. At the 7 o’clock position, there is a classic looking moon-phase indicator with the small-seconds display that runs around it. Finally, the leap year disk is revealed through an interesting aperture at the 6 o’clock position. The off-centered time sub-dial with stylish engraved Roman numerals is large enough to show hours and minutes at a glance. Just a few watchmakers are capable to arrange so many features at the dial with the mid-size diameter, and at the same time, to offer great readability, along with a stunning design.
In order to keep this aesthetic and functional perfection, A. Lange & Söhne revealed the tourbillon mechanism with the patented stop function only through a transparent sapphire crystal case-back. Just as the dial that is decorated by combining tremblage and relief engraving techniques, an in-house calibre L082.1 also deserves to be called – a piece of art.
Tourbillon and intermediate-wheel cocks are adorned with relief-engraving, the same as a robust central rotor, crafted in 21 karat gold with a platinum centrifugal mass. Furthermore, each of three train bridges is decorated with solarization. Finally, the upper side of the tourbillon cage is nicely polished. This self-winding movement oscillates at the frequency of 21’600 vibrations per hour and provides a power-reserve of 50 hours.
The case of the Lange 1 Tourbillon Perpetual Calendar Handwerkskunst watch is made of beautifully polished platinum case with the diameter of 41.9 mm. Combined with a black leather strap, this timepiece is a true example of the men’s elegance. First time presented in public at the “Watches & Wonders” Haute Horlogerie Exhibition in Hong Kong, this novelty will be exclusively available through the eleven international A. Lange & Söhne Boutiques.
