Experience the craft of A. Lange & Söhne in the Tourbillon (ref. 701.007), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in white gold and measuring 38.5 mm in diameter, with a thickness of 10 mm. The caseback is open, and the crystal is sapphire. At a glance, the dial balances texture and clarity: a blue tone, framed by stick / dot hour markers, and alpha hands. At its heart beats a proven engine: the L902.0 caliber. Produced in limited numbers, appealing to focused collectors. Introduced in 19941998. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
