A. Lange and Sohne 252.029 Richard Lange Jumping Seconds 18K White Gold Black Dial

A. Lange and Sohne's reference 252.029 Richard Lange Jumping Seconds is a masterclass in precision timekeeping, presented in an elegant 39.9mm 18K white gold case with a striking black dial crafted from solid silver. Released as a boutique-limited edition of just 100 pieces, this watch is highly coveted among collectors for its rare combination of classic German watchmaking and technical innovation. Its heart is the hand-wound L094.1 caliber, developed in-house and composed of 390 meticulously finished components. The distinctive feature of this model is its deadbeat, or "jumping," seconds complication—an homage to precision regulators of the past—allowing the central seconds hand to advance in discrete one-second increments. The power reserve of 42 hours, the intricate switching mechanism, and the exquisite finishing on the movement, viewable through a sapphire caseback, highlight the manufacture’s unyielding attention to detail. The absence of a date preserves the purity of the three-handed layout, drawing focus to the dial’s impressive clarity. Technically profound, echoes of historical marine chronometers, and produced in severely limited numbers, the 252.029 stands as one of the most intellectually rare and visually understated pillars in the Richard Lange lineage. Crafted for those who appreciate timekeeping ingenuity beyond aesthetic, it is a model that represents the pinnacle of A. Lange and Sohne's regulator philosophy. Like New with A.
