Stepping up in the same colour and case shape
The Master Collection has always sat at the calmer end of Longines' range — no complications for their own sake, no conspicuous case architecture, just a serious mechanical movement dressed for everyday wear. This reference makes that case quietly but persuasively. Eleven Top Wesselton diamonds take the place of applied indices, and the mother-of-pearl beneath them shifts between white and pale grey depending on the angle of the light, giving the dial a depth that printed lacquer cannot produce. At 30mm with a case that sits only 9.1mm from wrist to crystal, it carries almost nothing — 80 grams in total — and disappears under a cuff as easily as it works bare. The L592.5 inside is worth the mention: its silicon balance-spring makes the movement substantially more resistant to magnetic fields than a conventional hairspring, which matters more now than it did when most movements were regulated against fewer sources of interference. An exhibition caseback lets you see the decorated plate, which on a movement of this calibre is decoration that has earned its place.

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 45 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
15mm. 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 36.8mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as women's.
