Our remarks

A. Lange & Söhne Lange 1 – Ref. 151.021 – 18k Yellow Gold – Milanese Bracelet – Box & Papers – 2009 – Full Set – Service 2025

We are delighted to present this superb and increasingly desirable A. Lange & Söhne Lange 1 Reference 151.021, crafted in solid 18k yellow gold and fitted with its elegant Milanese-style bracelet — a rare and visually striking configuration that enhances the sculptural purity of one of the most important watch designs of the modern era.

Delivered in 2009, this example represents the quintessential expression of the Lange 1: a piece that embodies the renaissance of German fine watchmaking following the brand’s revival in the 1990s. The asymmetrical dial layout — with its off-center hour and minute display, oversized date, power reserve indicator, and subsidiary seconds — remains one of the most celebrated compositions in contemporary horology, instantly recognizable as a signature of Glashütte tradition reimagined through modern precision.

The warm champagne dial is the perfect complement to the 18k yellow gold case, showcasing applied markers, thermally blued screws, and the immaculate finishing that defines Lange’s craftsmanship. Each indication is placed with architectural intent, achieving a balance that feels both mathematical and poetic.

Inside beats the hand-finished Caliber L901.0, visible through the sapphire caseback. The three-quarter German silver plate, hand-engraved balance cock, gold chatons, and flawless anglage together form a movement that is considered one of the great mechanical works of the late 20th century. Notably, this example has a documented service scheduled and completed by Lange in 2025, ensuring optimal performance and long-term confidence for the next collector.

The Milanese bracelet — seldom seen on Lange 1 models — elevates the watch’s presence with an air of refined vintage character while remaining true to the manufacture’s understated philosophy. The 38.5 mm case retains excellent proportions, showcasing crisp bevels and a wonderfully preserved finish.

This full set includes:

- Original A. Lange & Söhne inner and outer presentation boxes

- Original warranty papers (2009)

- Service documentation (Lange, 2025)

- 24 month of Lange warranty!

Early yellow-gold Lange 1 examples with full sets and rare bracelet configurations are increasingly scarce, and pieces accompanied by recent manufacture service carry exceptional desirability for collectors of high German watchmaking.

“We absolutely adore these early Lange 1s — the mastery of design, the warm glow of yellow gold, and the awesome movement finishing make the 151.021 one of the most soulful expressions of modern Glashütte excellence.”
