LONGINES Ultra-Chron Square Date

— Geometry that divides the second —

In the late 1960s Longines introduced the Ultra-Chron, developed around a claim of accuracy within one minute a month and carrying the legendary 36,000 vph high-beat movement — ten beats per second.

— A square taken to its conclusion —

The geometric, unfussy square case makes for an intelligent wrist. A silver dial brushed vertically shifts quietly with the light, classical and forward-looking at once.

— Details that date it, in the best sense —

A date placed unusually at four-thirty, Longines' winged hourglass shining at twelve, and the lightning-bolt motif particular to the Ultra-Chron at six. The design thinking and the craft of the period are concentrated here.

— A classic carried forward —

Vintage, but entirely suited to daily use, and a good fit with modern dress. High accuracy and good form from Longines' golden period, neither of which has faded in half a century.
