Longines Spirit Zulu Time Chronometer 42 MM Automatic Black Matt Dial Watch L38124536

The Spirit Zulu Time traces back to Longines' first dual-time-zone wristwatch of 1925, which carried the Zulu flag on its dial. "Zulu" is the letter Z, aviation shorthand for universal time. This 42mm reference has a black matt dial and a bidirectional ceramic 24-hour bezel for tracking a second time zone.

It is powered by the exclusive Caliber L844.4, fitted with a silicon balance spring for magnetic resistance and chronometer-certified by the COSC, with a 72-hour power reserve.
