Stepping up in the same colour and case shape
The Spirit Zulu Time traces directly to a 1925 Longines dual-zone wristwatch — one of the earliest of its kind — whose dial carried the Zulu flag as a reference to the NATO phonetic alphabet letter designating universal time. Aviators still use that convention, and the watch was designed to serve exactly that reading: a second time zone set and read quickly, without interrupting the flight. At 42mm the proportions sit squarely in the working-tool tradition rather than the dress-pilot crossover, and the anthracite dial deepens considerably under low light, which is where the Super-LumiNova earns its place. The bidirectional bezel with its ceramic insert turns with enough resistance to stay where it is set, and the silicon balance-spring inside makes the movement both resistant to magnetic interference and COSC-certified — the two qualities most relevant to anyone wearing a watch around avionics equipment. Seventy-two hours of power reserve means a weekend off the wrist does not require resetting the GMT hand before the next departure.

Learn more about Longines
Auguste Agassiz began trading watches in Saint-Imier in 1832, but the modern company dates from 1860, when his nephew Ernest Francillon built a factory in the meadows beside the Suze — the longines of the local dialect — and consolidated the scattered outworkers of the region under one roof.
Longines registered its winged hourglass in 1889. It is the oldest watch trademark still in continuous use.
The company's identity was built on precision and on timing things in public. It supplied chronographs for the first modern Olympic events it timed in 1896, timed the 1912 Federal Gymnastics Festival with a broken-wire mechanism accurate to a hundredth of a second, and developed the photo-finish camera and the quartz timing devices used across twentieth-century athletics.
Its aviation associations are equally deep. Longines instruments were carried by Charles Lindbergh across the Atlantic in 1927, and the Hour Angle watch, designed to Lindbergh's own specification to simplify longitude calculation, remains in the catalogue. Amelia Earhart and Howard Hughes both navigated by Longines.
The house was among the most decorated at nineteenth-century observatory trials, holding numerous precision records. Since joining the Swatch Group in 1983 it has occupied the accessible-heritage position: exclusive ETA-based movements, archive-driven designs through the Heritage line, and volume that makes it one of the group's most important brands.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 72 hours fully wound — enough to sit off the wrist over a weekend and still be running.
Is it a men's or women's watch?
Listed as men's.
