Stepping up in the same colour and case shape
The Flagship collection first appeared in 1957 as Longines's formal dress line, and this reference is a deliberate return to that starting point. The caseback carries the argument most clearly: beneath the steel is a solid cover bearing an engraved 18-carat yellow gold medallion — a historical caravel ship set against Grand Feu blue enamel — which is not decoration added after the fact but a direct echo of what the original model wore. At 10.3mm thick, the case disappears beneath a shirt cuff without negotiation, which is the whole practical case for a watch of this type. The black dial reads with particular clarity because the rose gold-coloured dauphine hands and applied indices sit at enough contrast to register immediately, then reward slower attention in raking light. The alligator strap arrives with tone-on-tone stitching and a calfskin backing, and the pin buckle is engraved with the winged hourglass — a detail that takes a moment to notice and then becomes difficult to unsee. The L615, built on ETA 2895-2 architecture, is straightforward to service and carries a 50-hour power reserve — generous for the movement family, and enough that a watch worn Monday to Friday will still be running on Sunday morning.

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?
No. At 30m it will survive rain and handwashing, but not submersion of any kind.
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 50 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
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.
Is it a men's or women's watch?
Listed as men's, though at 38.5mm it sits in the range that suits anyone.
Cheapest place to buy
Goldsmiths is the only UK retailer we track stocking this reference, so there is nothing to compare it against today.
Who are Goldsmiths?
Goldsmiths has been selling watches in Britain since 1778 and is part of the Watches of Switzerland Group, which is listed on the London Stock Exchange. They are an authorised dealer, so a watch comes with the manufacturer’s own warranty.
