Stepping up in Longines's range
The Master Collection has been Longines's statement of classical watchmaking since 2005, a line that has always prioritised dial legibility and movement quality over ornamentation for its own sake. This 34mm version makes a particular case: twelve brilliant-cut diamonds totalling 0.055 carats replace printed indices on a beige sunray dial, and the effect is restrained rather than showy — the stones catch light without competing with the hands. The L888 movement underneath is the more interesting part of the story. Developed exclusively for Longines from an ETA base, it runs a silicon balance spring that resists magnetic fields far better than conventional hairsprings, and its frequency has been tuned to 25,200 vibrations per hour specifically to stretch the power reserve to 72 hours. That is an unusual trade-off, and a sensible one for a dress watch worn selectively. At 9.2mm the case sits genuinely flat — close enough to the wrist that it disappears under a cuff without catching. The fully polished bracelet and the triple-safety folding clasp are consistent with the dial's intentions: no raw edges, no visible mechanism until the push-piece is depressed. There is no lume on the hands or markers, which is a deliberate choice and the right one — the dial is meant to be read in daylight, and luminous material would interrupt its finish.

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.
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 72 hours fully wound — enough to sit off the wrist over a weekend and still be running.
What size strap does it take?
18mm. 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 women's, though at 34mm it sits in the range that suits anyone.
