Stepping up in the same colour and case shape
The Spirit line draws directly from the navigation watches Longines made for aviation pioneers in the early and mid twentieth century — the elongated lugs, the applied Arabic numerals, and the five small stars clustered at six o'clock are all deliberate references to that era, the stars having denoted chronometer-grade quality in historic Longines catalogue practice. This is not nostalgia for its own sake: the L888.4 that runs inside is a COSC-certified chronometer built on a silicon balance spring, which gives it real resistance to both magnetic fields and temperature swings in a way that earlier movements simply could not offer. At 40mm the case reads larger than that diameter suggests, because the lug-to-lug of nearly 50mm gives it the stretched, purposeful stance of a proper pilot's watch. The 12.2mm thickness keeps it surprisingly wearable under a cuff for a watch with that much wrist presence. The matte green dial with its sandblasted hands is calm and easy to read, and the Super-LumiNova on both the markers and the hands charges quickly and holds well into the evening. The matte brown calf strap with cream contrast stitching suits the military-instrument character without leaning too hard into costume territory. The 72-hour power reserve means setting the watch on a Friday evening and finding it still running Monday morning — a practical detail the movement's architecture earns through its altered beat rate rather than through any increase in size.

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.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
How 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.
What size strap does it take?
21mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 49.7mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
