Inside A. Lange & Söhne: Wilhelm Schmid on Lumen & Annual Calendar | Watches & Wonders 2026

At Watches & Wonders 2026 in Geneva, A. Lange & Söhne unveiled two new calendar-focused timepieces — each reflecting the brand’s philosophy of precision, restraint, and mechanical depth. We spoke with CEO Wilhelm Schmid about the thinking behind these novelties, the evolution of Lange’s calendar watches, and why the brand continues to focus on substance over spectacle. The highlights: – The Lange 1 Tourbillon Perpetual Calendar “Lumen” A highly complex piece combining tourbillon and perpetual calendar within the unmistakable Lange 1 layout. The semi-transparent dial allows luminous elements to charge and remain fully legible in the dark — a rare fusion of technical innovation and aesthetic clarity. – The Saxonia Annual Calendar A more classical approach: reduced, elegant, and highly wearable. A compact case paired with Lange’s signature outsize date and a clean calendar display — a reminder that complexity at Lange is always guided by legibility and proportion.
