A. Lange & Söhne Grand Langematik – 309.031

Crafted in solid 18k rose gold, this 40mm timepiece features a black solid dial with gold-tone index hour markers and sleek gold-tone hands, complemented by a patented large double-window date at the top of the dial—a hallmark of A. Lange & Söhne watches. The watch is powered by the in-house automatic movement L921.2 SAX-0-MAT, renowned for its precision, 46-hour power reserve, automatic winding mechanism with a Zero-Reset function, and beautifully finished three-quarter German silver plate with a hand-engraved balance cock, visible through the sapphire crystal caseback. The elegant piece is paired with a high-quality black alligator leather strap and secured with an 18k rose gold tang buckle, matching the case material.
