Longines Spirit Flyback Titanium 42mm Mens Watch Grey
Ref. L38211536
Sits in Longines’s upper tier here — more premium than three quarters of the Longines watches we list, which start at £900.
Price range £900 to £22,850 across 249 Longines watches in stock.The flyback chronograph has been part of Longines since 1935, when the brand first patented the function for use in aviation timing. The Spirit line draws on that history directly, and this titanium version is where that lineage meets a modern reading of the pilot's brief: an instrument-focused dial, a ceramic bezel insert, and a movement certified to COSC standards. The calibre L791.4 at its core carries a silicon balance-spring, which makes it resistant to magnetic fields that would trouble a conventional lever escapement — a detail that matters more now than it did when the flyback was designed for cockpits. At 49.5mm lug to lug and 17mm tall, this is not a watch that pretends to disappear. It sits with clear presence. What saves it from feeling heavy is the Grade 5 titanium throughout — case and bracelet together come to 124.7 grams, which is a meaningful reduction against a steel equivalent of the same build, and you notice it across a full day. The anthracite dial reads cleanly at distance in flat light and sharpens considerably in the dark, where the lume on the Arabic numerals and hands performs well above average for this category. The bracelet has a tool-free quick-release on the underside — a small thing that owners tend to appreciate more than they expect, once they actually use it.

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 68 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 49.5mm, which suits wrists from roughly 16.5cm (6½ 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.
