There are minimal swirl marks with no major damage to case, dial and movement. Watch was recently serviced in 2023 and the movement is in fantastic working condition.
Our Thoughts:
With around 200 pieces ever produced, the Lange 1 101.027X is one of the most sought after pieces with the stamped dial displaying delicate texture, adds depth and character and is only the second iteration ever to feature a stamped dial. This rare dial variation is paired with hand-polished blued steel hands creating a striking contrast against the crisp white gold case and subtly elevating its aesthetic.
Inside the 38.5mm case, the watch is powered by the legendary caliber L901.0, a hand-wound movement designed to perfection. With its three-quarter plate, hand-engraved balance cock, and signature twin mainspring barrels for a 72-hour power reserve, the movement embodies A. Lange & Söhne’s unwavering commitment to precision and artistry. Visible through the sapphire caseback, it’s a reminder of the brand’s unparalleled finishing and attention to detail.
For collectors with a deep appreciation for rarity and independent watchmaking, the Lange 1 101.027X is a true grail for those who value the artistry and innovation behind every A. Lange & Söhne creation. Few watches capture the essence of independent watchmaking as powerfully as the Lange 1, and this model is a shining example of why the brand continues to sit at the pinnacle of haute horology.
