A. Lange & Söhne Grand Lange 1 Moon Phase 139.025 Platinum Silver Dial (2026)

In Platinum with a Silver dial, the Grand Lange 1 Moon Phase 139.025 is the most restrained version of a watch built around one idea: setting the moon inside the hour and minute circle, where A. Lange & Söhne can show it large against a starry sky. The Grand Lange 1 takes the asymmetric layout of the 1994 Lange 1 to 41 mm, and the moon phase makes use of that extra room without adding an opening to the dial.

On the dial of solid silver, the moon disc turns beneath the hours and minutes, beside Lange's outsize date at upper right and the power-reserve indicator. The 41 mm Platinum case is 9.5 mm high with a sapphire caseback over the hand-wound movement, which Lange assembles twice, as it does every movement. A black alligator strap and Platinum prong buckle complete it.
