The A. Lange & Söhne 1815 Chronograph reference 414.031 is widely regarded as one of the finest manually wound chronographs ever created. Combining traditional German watchmaking with exceptional movement architecture, this masterpiece embodies the precision, craftsmanship, and timeless elegance for which A. Lange & Söhne is celebrated.

Crafted from 18k rose gold, the 39.5mm case features beautifully balanced proportions and houses the legendary in-house Calibre L951.5. Visible through the sapphire crystal caseback, the movement showcases exquisite hand-finishing, including untreated German silver bridges, hand-engraved balance cock, polished levers, and a column-wheel chronograph mechanism admired by collectors worldwide.

The striking black dial is complemented by Arabic numeral hour markers and elegant chronograph registers, creating superb legibility while maintaining the classic aesthetic of the 1815 collection. Paired with a black alligator leather strap and rose gold buckle, this timepiece delivers sophistication both on and off the wrist.

Presented in very good pre-owned condition, this example comes complete with its original watch, box, and papers.
