Longines Legend Diver 39mm Mens Watch Green
Ref. L37644066
Sits in Longines’s upper tier here — more premium than three quarters of the Longines watches we list, which start at £1,050.
Price range £1,050 to £22,850 across 194 Longines watches in stock.The Legend Diver traces its shape to a 1959 super-compressor case design, and this 39mm edition is essentially the correction of a longstanding complaint. The 42mm version that ran for years was too long across the wrist for most people — that 52mm lug-to-lug span simply did not suit average sizing — and Longines has solved it here by bringing the lug-to-lug down to 47mm with a curve that pulls the watch into contact with the wrist rather than bridging over it. The result wears with the close, settled feel of something much older and smaller, which is precisely what the mid-century styling calls for. The L888.6 inside is COSC-certified and built around a silicon balance spring, which gives it meaningful resistance to magnetic fields and contributes to the 72-hour power reserve — useful assurance when the watch comes off for a weekend. The green lacquered dial and internal diving flange operated through the top crown carry the super-compressor identity intact; the dual-crown layout is functional architecture, not decoration. On the bracelet, the beads-of-rice links suit the vintage character, and the clasp includes a tool-free micro-adjustment that lets the fit shift without removing the watch — the kind of detail that becomes quietly indispensable as temperatures change through the day.

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 300m it is rated for swimming, snorkelling and recreational 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?
20mm. 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 47mm, 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 men's, though at 39mm 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.
