About the A. Lange & Söhne Grand Lange 1
A. Lange & Söhne reestablished itself in 1994 after decades of dormancy and immediately redefined German haute horlogerie with the original Lange 1, whose hallmark asymmetric dial and oversized date display became instant icons. The Grand Lange 1 scales that blueprint up to a 41 mm case, lending greater presence on the wrist while retaining the meticulous three-quarter plate construction, hand-engraved balance cock, and double-movement winding architecture that distinguish every Lange timepiece. The Moon Phase variants add a precisely engineered lunar display said to require correction only once every few centuries, elevating the Grand Lange 1 from an exceptional dress watch to a genuine horological statement. The Lumen edition, reference 139.035F, takes the concept further with a dial material that glows in the dark, demonstrating Lange's willingness to push traditional boundaries within an otherwise classically oriented house.
What to Look For
Buyers should pay close attention to case material and dial color, as each combination carries its own character and market premium: platinum references such as 139.025 typically command a higher price floor than gold variants, while rarer configurations like the Lumen 139.035F attract significant collector interest. Within the moon-phase subfamily, confirming whether a piece is brand new in full set or pre-owned with box and papers is critical to value, and the argenté, rhodié silver, and ivory argenté dials each age and photograph differently, so reviewing high-resolution images before purchase is strongly advised.
Frequently Asked Questions
What is the case size of the Grand Lange 1 and how does it compare to the standard Lange 1?
The Grand Lange 1 is presented in a 41 mm case, making it noticeably larger and bolder than the original Lange 1. The increased diameter gives more room for the signature outsize date display and, in moon-phase models, the lunar complication, while preserving the asymmetric dial layout that defines the entire Lange 1 family.
Which Grand Lange 1 references are available for sale at Bizak and Co.?
Bizak and Co. currently carries both time-only references including 137.038 in white gold and 137.033 in pink rose gold, as well as moon-phase references 139.021 in yellow gold, 139.025 in platinum, 139.032 in pink rose gold, and the special Lumen edition 139.035F in platinum. Several of these pieces are brand new, and all have been authenticated prior to listing.
What makes the Grand Lange 1 Moon Phase Lumen edition different from the standard moon-phase models?
The Grand Lange 1 Moon Phase Lumen, reference 139.035F, features a specially treated dial that stores light and emits a luminous glow in darkness, allowing the moon-phase and time displays to remain legible without a light source. This distinguishes it from the more traditionally finished argenté and rhodié silver dials found across the rest of the moon-phase lineup and makes it a particularly sought-after collector's piece.
