Quick TakeThis isn't just a watch; it's a trusty co-pilot for your life's adventures. The Zulu Time is built tough with a steel case and a hardy ceramic bezel ready for any cockpit or boardroom. Its black dial is clean and clear, day or night, thanks to a healthy dose of Super-LumiNova. Forget winding it every day; its heart beats for a full 72 hours on its own. With the ability to track another time zone, you're always connected, no matter where you land. It’s a serious tool that doesn't take itself too seriously.

DescriptionThe timepiece presents a round case architecture constructed from stainless steel, with a diameter of 42.00 mm, a thickness of 14.10 mm, and a total weight of 164.0 g. The lug distance is specified at 22 mm, with a lug-to-lug dimension of 49.40 mm. A key functional element is the bi-directional rotating bezel, which incorporates a ceramic insert. The integrity of the case is ensured by a screw-in crown, contributing to a water resistance rating of 10 bar. Protecting the dial is a scratch-resistant sapphire crystal, enhanced with multiple layers of anti-reflective coating applied to both its upper and lower surfaces. The dial itself is rendered in a black matt finish, featuring applied Arabic numerals as hour markers and pink hands, all treated with Swiss Super-LumiNova® for low-light visibility.

Powering the instrument is the Caliber L844.4, a self-winding mechanical movement. This automatic system operates at a frequency of 25,200 vibrations per hour and incorporates a monocrystalline silicon balance-spring, providing a power reserve of approximately 72 hours. The movement's complications include hours, minutes, seconds, a date display, and a 24-hour hand with a dedicated time zone mechanism. The watch is secured to the wrist by a stainless steel bracelet equipped with a double safety folding clasp and a push-piece opening mechanism. For user convenience, the bracelet features the Longines interchangeable system, allowing for tool-free strap changes.
