A. Lange and Söhne 115.031 (Pre-owned - Good) — USD 37,744 on eBay

The A. Lange & Söhne Grand Lange 1 reference 115.031 in 18kt rose gold with a black dial is a timepiece of considerable visual impact. The combination of rose gold's inherent warmth with the depth and drama of a black dial creates a striking tension -- a watch that is simultaneously inviting and commanding. At 41.9mm, the Grand Lange 1 provides a generous canvas for the iconic asymmetric layout, and the black dial uses that canvas to maximum effect, with each element -- the outsize date, the off-center time display, the small seconds, the power reserve indicator -- appearing to emerge from darkness. The purpose-built caliber L095.1 provides 72 hours of hand-wound power reserve, maintaining the practical autonomy that has always been a defining characteristic of the Lange 1 family. The movement's construction reflects three decades of refinement since A. Lange & Söhne's 1990 refounding: the twin-disc outsize date mechanism switches instantaneously at midnight, the power reserve indication is linear and easy to read, and the overall timekeeping precision meets the most demanding standards. Through the caseback, the lavishly finished movement presents a marked contrast to the dark drama of the dial side. Rose gold and black is a combination that has earned its place among the classics of modern watch design, and the Grand Lange 1 executes it with particular conviction. Reference 115.031 appeals to the collector who wants a Lange 1 with substance and presence -- someone who appreciates the design's intellectual rigor but also wants a watch that makes an impression when the cuff pulls back. A. Lange & Söhne built this watch for exactly that person, and they built it superbly.
