A.Lange & Söhne 1815 Rattrapante Perpetual

Lange A. Lange & Sohne makes excellent craftsmanship a masterpiece of art with its unique Handwerkskunst watch. The new 1815 Rattrapante Perpetual Calendar Handwerkskunst’s dial and openable caseback are made of white enamel 18K gold with blue enamel and decorated with magnificent reliefs. The noble and outstanding movement not only has a unique decoration, but also combines two wonderful complex functions of a chronograph chronograph and a perpetual calendar with a moon phase display.

The 1815 Rattrapante Perpetual Calendar shines when it is born: at the Geneva Salon in January 2013, the wrist achieved a high level of technology and aesthetics due to its combination of classic complications, this wrist Watches are highly regarded by watch enthusiasts and regarded as a subtle achievement in the field of precision mechanical watchmaking. In the same year’s Grand Prix d’ Horlogerie de Genève, this watch not only became the champion of the category “large complex functions”, but also won the “Public’s Choice Award”.

This extraordinary precision chronograph lays the ideal foundation for a limited edition of 20 Handwerkskunst versions. This is Lange’s sixth work titled ‘Handwerkskunst’, which reflects the unique art deco characteristics of this series of limited watches on the movement, dial and case. 1815 Rattrapante Perpetual Calendar Handwerkskunst brings exciting challenges to decorators, engravers, and enamelists: master craftsmen use rare and even nearly lost techniques and creative ideas to present Lange’s world-famous magnificent decoration.

This is Lange’s first watch with a fusion of enamel art and engraving on the dial. Solid white 18K gold becomes the base of the dark blue enamel, and the embossed stars on it continue the gorgeous shape of the moon phase display. Enamel Arabic numerals are harmoniously combined with rhodium-plated white 18K gold hands, calendar display and power reserve indicator. In addition, the enamel color also echoes the hands of the moon phase disk and the integral disk. Various details are complemented by four inset white 18K gold and silver white dials. The chronograph hands are made of 18K gold-plated steel with a unique hue, while the dial is decorated with a silver-white flange with a traditional train track minute scale.

The moon theme continues in the openable back cover that protects the sapphire crystal back cover, which depicts the moon goddess, and uses the relief and ‘tremblage’ engraving to outline the ancient and mysterious moon incarnation. This badge shows the charming features of the moon goddess: the ethereal veil, the crescent moon crest, and the torch shining in the dark. It is surrounded by nine embossed stars and blue enamel relief clouds.

The artistic movement decoration reveals the technical ambitions of this watch in terms of complications. The German silver wheel bridge presents the grainy texture of a classic pocket watch movement. The relief and ‘tremblage’ engraving on the joystick, flip cover, chronograph bridge, chasing hands and balance plate all outline the star pattern of the dial. Other details are also meticulous. The manually wound L101.1 calibre, composed of 631 parts, is meticulously crafted to meet Lange’s strict standards.

The tracing chronograph can measure lap speed and perform continuous time counting. It is controlled by two column wheels: one controls the chronograph structure and the other control can be started by the 10 o’clock position button and the visible tracing device The perpetual calendar device displays correctly up to 2100, including leap years. The moon phase display is located at the small seconds at 6 o’clock, with an accuracy of 122.6 years. The manual winding movement has a power reserve of 42 hours, and the power reserve indicator reminds the wearer when to wind the watch.

The 1815 Rattrapante Perpetual Calendar Handwerkskunst’s 41.9mm white 18K gold case is engraved with a limited number logo, and a blue-gray alligator strap with a white 18K gold folding buckle.
