Stepping up in the same colour and case shape
The Spirit collection takes its cues from the navigational instruments Longines supplied to aviators during the great age of flight — clean dials built for fast reading under pressure, chronometer-grade movements where a slip in accuracy had consequences. This 37mm iteration sits at the more considered end of the Spirit range, its 44.8mm lug-to-lug keeping it close to the wrist in a way the 40mm and 42mm versions cannot quite manage, and making it genuinely wearable across a wider range of wrists. The sunray blue dial works differently as the light shifts, the applied Arabic numerals and sandblasted hands reading sharply against it regardless of angle. Five applied stars sit low on the dial — a traditional mark of chronometer certification, here earned rather than decorative, since the L888.4 inside carries COSC approval and a silicon balance-spring that resists magnetic interference. The 72-hour power reserve means a watch left off over a weekend will still be running on Monday morning. The bracelet swaps straps without tools via quick-release spring bars, and the triple-safety clasp closes with the kind of firmness that does not leave you second-guessing it mid-activity.

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?
19mm. 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 44.8mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
