Longines Ultra-Chron Classic Automatic – L2.937.4.72.6

The Longines Ultra-Chron Classic Automatic (Ref. L2.937.4.72.6) is a modern homage to a groundbreaking chapter in horological history. In 1968, Longines introduced the Ultra-Chron Diver—the first dive watch equipped with a high-frequency movement. This innovation built upon decades of Longines expertise in precision timekeeping, dating back to 1910 when the brand created the first high-frequency device capable of measuring 1/10th of a second. By 1959, Longines had perfected the first high-beat wristwatch movement, setting new benchmarks in accuracy and performance.

The new Ultra-Chron Classic draws inspiration from the distinctive design and technical prowess of its 1968 predecessor while integrating cutting-edge advancements for today’s wearer. Housed in a 40 mm stainless steel case, this automatic timepiece features a striking sunray silver dial adorned with applied indexes and polished silver hands, exuding understated sophistication. Protected by a scratch-resistant sapphire crystal with anti-reflective coating on both sides, the watch ensures clarity and durability from every angle.

Powered by the exclusive Longines Caliber L836, the Ultra-Chron Classic beats at an impressive 36,000 vibrations per hour, offering a remarkable blend of precision and reliability. The monocrystalline silicon balance spring enhances resistance to magnetic fields and ensures stable timekeeping, while the 52-hour power reserve provides lasting performance.

Completing the look, a stainless steel bracelet with a double security folding clasp and micro-adjustment system offers both comfort and style. Water-resistant to 50 meters, this chronometer-certified masterpiece embodies Longines’ legacy of innovation, accuracy, and timeless design.

The Longines Ultra-Chron Classic is more than a watch—it’s a celebration of technical excellence and heritage, crafted for those who value precision and elegance in every moment.
