A. Lange & Söhne 'Jumping Seconds'

Overall Condition: Excellent condition overall. Case shows only faint signs of wear. Dial and handset are in excellent condition. Factory strap and pin buckle are like-new.

A. Lange & Söhne occupies a rare position in modern watchmaking. Plenty of manufactures speak about craftsmanship and precision; Lange simply demonstrates it. Nearly everything emerging from Glashütte feels engineered with a degree of discipline bordering on obsessive, yet the technical rigor rarely comes at the expense of beauty.

Within the catalog, the Richard Lange collection represents perhaps the purest expression of that philosophy. Named for Ferdinand Adolph Lange’s eldest son, an accomplished watchmaker whose research included advances in balance springs and temperature compensation, the collection is less concerned with spectacle than with chronometry: watches fundamentally designed around the precise measurement of time.

The Richard Lange Jumping Seconds Reference 252.056 makes that pursuit of precision visible. Limited to just 100 pieces, it pairs a 39.9mm 18K white-gold case with a solid pink-gold dial arranged in a distinctive regulator-style configuration. Three overlapping displays separate hours, minutes, and seconds, recalling historic precision instruments while producing one of Lange’s most unusual and immediately recognizable dial designs.

The star is that enormous seconds display. Rather than sweeping across the dial, its hand advances in exact one-second increments. This “deadbeat” or jumping-seconds indication isn't simply a visual trick. It is driven by a constant-force mechanism that delivers energy to the escapement in controlled one-second intervals, helping maintain consistent amplitude as the mainspring unwinds. A small triangular aperture at the intersection of the three displays serves as a low-power warning, turning red when approximately ten hours of reserve remain.

Inside is the manually wound Calibre L094.1, a movement developed around this unusual chronometric architecture. Beyond its constant-force mechanism, Lange incorporated a clever zero-reset function: pull the crown and the balance stops while the seconds hand instantly returns to zero, allowing the watch to be synchronized precisely to a reference time. The movement offers approximately 42 hours of power reserve.

Turn the watch over and Lange's particular brand of mechanical theater takes over. Through the sapphire exhibition caseback, the architecture of the L094.1 is revealed alongside the hand-finishing that has become a Glashütte signature: polished and beveled components, decorated bridges, screwed gold chatons, blued screws, and hand engraving. It's a striking contrast to the dial's intellectual restraint.

This example is fitted to a brown leather strap with a signed 18K white-gold pin buckle and is accompanied by an especially desirable assortment of factory accessories, including its inner and outer boxes, papers, and pamphlets.

The Richard Lange Jumping Seconds doesn't need to announce its complexity. Look closely at that enormous seconds hand. The deliberate tick, tick, tick says enough.
