Description
The most distinctive exterior feature is the case made of 18-karat Honeygold (). This Lange-patented material is significantly harder and more scratch-resistant than conventional gold alloys and is distinguished by a warm, subtle sheen whose color falls between Yellow and Rose Gold. With a diameter of 38.5 mm and a height of just 10.2 mm, it is the perfect embodiment of a classic dress watch.
Material: The dial is made of solid Silver and finished in a light Arganté tone.
Play of Light: The Roman numerals and hands are color-matched to the Honeygold case. Particularly noteworthy is the outer Ring of the dial with its fine railway-track minute scale, which gives the watch an almost architectural depth.
The Big Date: The iconic Lange double-window date at 12 o’clock ensures outstanding legibility and forms the anchor point of the symmetrical layout.
At its heart is the L922.1 automatic movement, specially developed to integrate the perpetual calendar and the patented SAX-0-MAT mechanism.
Zero-Reset: When the crown is pulled out, the seconds hand immediately jumps back to the zero position. This enables the time to be synchronized to the exact second.
Perpetual Calendar: The mechanism correctly recognizes the varying lengths of the months and leap years through 2100. It features a moon-phase display calculated with such precision that it only needs to be corrected by one day after 122.6 years.
Micro-Rotor: The eccentrically mounted 21-karat gold rotor with a platinum oscillating weight enables the slim design and provides a view of the hand-engraved balance bridge.
Each of the 100 examples is assembled twice according to the strictest Lange standards.
Finishing: The three-quarter plate made of untreated German silver, the hand-polished gold chatons, and the thermally blued screws turn the movement into a visual feast, visible through the sapphire crystal caseback.
Conclusion: Reference 310.050 is the “endgame” for lovers of Saxon fine mechanics. The combination of the rarity of Honeygold, the limitation to 100 pieces, and the highly functional SAX-0-MAT movement makes it one of A. Lange & Söhne’s most sought-after modern classics.
