Stepping up in the same colour and case shape
The Spirit collection arrived as Longines' argument that aviation-style tool watches needn't sacrifice movement quality for the category. At the centre of this one is the L688.4, a column-wheel chronograph calibre built around a silicon balance-spring, which gives it a meaningful resistance to magnetic fields that earlier lever-escapement movements could not match. COSC certification on top of that is an objective measure of daily rate accuracy, not a marketing addition. At 42mm with a 51.40mm lug-to-lug span, this wears exactly as large as it looks — no flattery from an unusually short lug. The 16.50mm case thickness is the trade-off a column-wheel movement of this complexity demands, and on a medium to large wrist it sits with authority rather than awkwardness. The stepped case, with its alternating brushed flanks and polished bevels, gives the dial a framed, purposeful quality in changing light, and the pilot numerals with their LumiNova coating read with the kind of immediacy that justifies the aviation reference. The quick-release bracelet system is worth noting for what it changes in daily use: swapping to a strap requires no tools and no watchmaker, which on a watch with a 22mm lug width opens a wide aftermarket. The triple-safety clasp handles security without ceremony, releasing cleanly on the push-piece.

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 66 hours fully wound — enough to sit off the wrist over a weekend and still be running.
What size strap does it take?
22mm. 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 51.40mm, which suits wrists from roughly 17.5cm (7 inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's.
