Longines Ultra-Chron Classic, reference L2.537.4.72.6
Longines's Ultra-Chron Classic in reference L2.537.4.72.6, offered new here at $4,000. On paper: an automatic movement, date to read alongside the time, a 37mm stainless steel case and a stainless steel bracelet to wear it on.
Case, dial and crystal
Ref. L2.537.4.72.6 comes in stainless steel and measures 37mm — a steel case is the least expensive of these to refinish. The dial is gray, read through sapphire — sapphire does not scuff the way acrylic does. L2.537.4.72.6 is the reference to keep with the watch: it identifies the exact configuration rather than the model family.
Ref. L2.537.4.72.6: movement and functions
Automatic is how the Longines Ultra-Chron Classic is powered — worn regularly it winds itself and simply runs. Alongside the hours and minutes: a date display.
Fit and feel
This Ultra-Chron Classic is fitted with a stainless steel bracelet — sized with links rather than holes. This is the least demanding size range there is — and the Longines Ultra-Chron Classic is 37mm.
Condition, set and warranty
This Ultra-Chron Classic, ref. L2.537.4.72.6, has not been owned before. As listed, original box and papers are included. The record notes that the L2.537.4.72.6 still carries its factory warranty.

Notes on this Ultra-Chron Classic
New 37mm Longines Ultra-Chron Classic (L2.537.4.72.6)
In 1968, Longines launched the Ultra-Chron Diver, the first dive watch equipped with a high-frequency movement. At the time, Longines had already established itself as a pioneer in high-frequency technology. As early as 1910, the winged hourglass brand created the first high-frequency timekeeping device capable of measuring 1/10th of a second. In 1959, Longines developed the first high-beat movement for a wristwatch, an observatory chronometer that set new records in terms of accuracy. The new Ultra-Chron is inspired by the aesthetic codes and professional diving features of the 1968 model. These chronometer-certified watches are powered by an exclusive Longines calibre equipped with a silicon balance-spring and resistant to magnetic fields.
