This is a 950 platinum A. Lange & Sohne Lange 1 Moon phase 109.025. The alligator strap has a platinum buckle, and a scratch resistant sapphire crystal. It has a large screw down winding crown, a corrector for the moon phase on the left side case band at 8 o'clock, and a rectangular push button that adjusts the date at 10 o'clock. It includes an exhibition sapphire display case back secured with 6 screws, and engraved "A. LANGE & SOHNE – GLASHUTTE, SA.," a serial number and hallmarks. The 38.5mm diameter solid three-body case, rounded bezel, and curved lugs, are polished/brushed. The dial is silver with applied white gold Roman numeral hour markers at the quarter hours, diamond-shaped indexes, and luminous alpha hands. There is a small seconds sub dial inside the moon phase aperture, and a pushbutton for correcting the date at 10 o'clock, with a large double-date aperture at 1 o'clock, and a 72-hour power reserve sector at 3 o'clock with a blued indicator hand and a luminous insert. It's water resistant to 30 meters/100 feet, and the 10.4mm thick case, dial, and movement are all signed.

This A. Lange & Sohne Lange 1 Moon phase 109.025 has a mechanical manual winding Lange caliber L 901.5 movement that's fashioned from Glashütte (untreated German silver) 3/4 plate, with fausses cotes and Cotes de Geneve embellishment. It's constructed with 54 jewels and includes 9 screw-mounted gold chatons, a straight-line lever escapement, blued screws, and a monometallic balance adjusted to cold, heat, and 5 positions. There is a self-compensating flat balance spring, a swan neck micrometer regulator, a hand engraved balance bridge and fan-shaped balance cock, a shock absorber mechanism, and an omega-shaped whiplash precision index adjuster. The mechanism oscillates at a frequency of 21,600 vph (3 Hz).

The moon phase display of this watch reproduces the progression of the moon in two ways: The lunar disc continuously revolves, making it so precise that it only deviates one day after having run without interruption for 122.6 years.
