Longines Ultra-Chron Classic

The Longines Ultra-Chron Classic is a modern reimagining of the brand’s historic 1967 high-frequency timepiece, presented with a choice of 37mm or 40mm case sizes. Balancing heritage aesthetics with contemporary materials and chronometric performance, this watch exemplifies Longines’ legacy as a pioneer in precision timing. With its domed silver sunray dial, trapezoidal date window, and high-beat calibre L836.6, the Ultra-Chron Classic offers a faithful yet forward-looking interpretation of the original: refined, technically advanced, and built for everyday elegance.
Crafted from stainless-steel, the case of the Longines Ultra-Chron Classic is available in two refined sizes: 37mm and 40mm in diameter, both maintaining a slim profile under 11mm in thickness. The case design embraces vintage proportions while integrating contemporary construction and finishing. With a mix of polished and brushed surfaces, the rounded contours are complemented by short lugs that ensure a balanced and comfortable fit on the wrist.
Turning the watch over reveals a solid screw-down caseback adorned with the historical Ultra-Chron logo, a nod to the original 1967 model. While not transparent, the caseback underscores Longines’ decision to emphasize heritage authenticity and durability over modern display trends.
The signed crown at 3 o’clock is proportionally sized and easy to grip, blending seamlessly into the case profile while offering practical functionality. A domed sapphire crystal with anti-reflective treatment protects the dial, enhancing legibility from multiple angles. Water-resistance can reach up to 50 meters (165 feet), ensuring reliable protection for everyday use.
The dial of the Longines Ultra-Chron Classic remains faithful to its 1967 predecessor, showcasing a beautifully domed silver sunray finish that radiates elegance and depth. The curvature of the dial surface plays with light dynamically, offering varying tonalities depending on the viewing angle. It captures the vintage spirit without veering into nostalgia, presenting a clean and timeless aesthetic.

Polished and applied baton-style hour markers contribute to the refined look, accompanied by a distinctive trapezoidal date aperture at 3 o’clock, as a direct nod to the original Ultra-Chron model. The hour and minute hands are faceted and rhodium-plated for maximum clarity, while the slender central seconds hand adds a sense of quiet precision to the overall composition.All hands and markers are filled with Super-LumiNova, ensuring legibility in low-light conditions. A printed minute track around the outer edge provides subtle functionality, maintaining a balanced layout. The restrained typography, crisp detailing, and silver-on-silver palette underscore Longines’ commitment to heritage-driven design, elevated by modern manufacturing finesse.
