About the A. Lange & Söhne Lange 1 Perpetual Calendar
The Lange 1 debuted in 1994 as the watch that announced the revival of A. Lange & Söhne after decades of dormancy, introducing a deliberately asymmetric dial layout and an outsize date that became instantly recognizable hallmarks of the Saxon manufacture. The Perpetual Calendar complication elevated that foundation into grand-complication territory, adding a mechanism that accounts for months of unequal length and leap years without requiring manual correction until the year 2100. Presented at 41.9 mm across and available in white gold, platinum, and pink rose gold, the collection pairs precious-metal case choices with carefully coordinated dials—including high-contrast black and sophisticated grey—to suit a range of collecting tastes. The result is one of the most legible and architecturally distinctive perpetual calendars in the entire watchmaking canon.
What to Look For
Buyers comparing references within the Lange 1 Perpetual Calendar line should pay close attention to case material and dial color, as these pairings drive significant price and aesthetic differences: the platinum 345.036 with its black dial commands particular collector attention for its contrast and the rarity of platinum in the lineup, while the pink rose gold 345.033 with a grey dial offers a warmer, softer presentation. Condition designations matter equally—brand-new examples such as the 345.036 and 345.033 carry full documentation and unworn status that support long-term value, whereas pre-owned pieces like the 345.056 can represent meaningful entry points into this complication at a more accessible price.
Frequently Asked Questions
What case size is the Lange 1 Perpetual Calendar?
The Lange 1 Perpetual Calendar measures 41.9 mm in diameter, a size that gives the asymmetric dial layout and its multiple subdials the room needed for optimal legibility. All references currently offered at Bizak and Co., including the white gold 345.056, platinum 345.036, and pink rose gold 345.033, share this same 41.9 mm case diameter.
What precious metals are available for the Lange 1 Perpetual Calendar?
The collection is offered in white gold, platinum, and pink rose gold, each paired with a distinct dial to create a cohesive aesthetic rather than simply changing the metal. Platinum examples such as the 345.036 with a black dial and pink rose gold examples such as the 345.033 with a grey dial are currently available brand new at Bizak and Co.
Is the Lange 1 Perpetual Calendar a good investment?
A. Lange & Söhne perpetual calendars are produced in limited numbers from a small, independent German manufacture, which historically supports strong secondary-market values. Brand-new references in platinum and precious metals with full documentation tend to hold value particularly well, and the horological significance of the Lange 1 platform adds collector desirability beyond its complication alone.
