Stepping up in the same colour and case shape
The Legend Diver traces its shape directly to Reference 7042, a 1960 Longines dive watch built on the Super Compressor principle, where water pressure actively improved the seal rather than working against it. The modern reissue, launched in 2007 and expanded to include this steel-bracelet configuration in 2020, preserves the feature that made the original genuinely unusual: the rotating dive bezel sits inside the case, protected from knocks and accidental movement by the case itself. It is a Longines invention, and it remains one of the cleaner solutions to the problem of bezel security. At 42mm wide and only 12.7mm thick, the watch sits flatter than its depth rating would suggest — 300 metres of resistance with a profile that clears a shirt cuff without difficulty. The dial is a polished black lacquer, and the domed crystal rises sharply from the case, which curves upward to meet it so that the whole top surface reads as one continuous arc. That shape is striking at a direct angle and will compress the dial slightly when viewed from the side. The L888 movement, visible through the exhibition caseback, runs a 72-hour power reserve and displays it on the dial alongside the date — a useful pair of complications on a watch that doubles as daily wear.

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?
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.
Is it a men's or women's watch?
Listed as men's.
