The Longines Ultra-Chron Classic Automatic 37mm L2.537.4.72.2 is a timepiece that speaks to collectors who value both heritage and precision. Drawing inspiration from the groundbreaking 1968 Ultra-Chron Diver, this modern classic pays homage to Longines’ long-standing expertise in high-frequency watchmaking, a tradition that began as early as 1910 when the brand pioneered devices capable of measuring 1/10th of a second.

Inside the refined 37 mm stainless-steel case beats Longines’ exclusive high-frequency calibre with a silicon balance spring, a movement that echoes the record-setting observatory chronometers of 1959. Certified as a chronometer, it delivers exceptional accuracy and robust resistance to magnetic fields-qualities that made the original Ultra-Chron legendary among professional divers.

The sunray silver dial, vintage-style markers and elegantly tapered leather strap capture the sleek aesthetic of the 1960s while offering contemporary reliability. Whether you’re drawn to its rich history, its technical excellence or its understated design, the Longines Ultra-Chron Classic Automatic 37mm L2.537.4.72.2 is a compelling choice for enthusiasts seeking a Swiss watch with proven performance and timeless appeal.
