Stepping up in the same colour and case shape
The PrimaLuna takes its name and its shape from the moon, and the design brief has been followed with some consistency: the case is round and softly proportioned, the dial carries a sunray finish in a pale blue that shifts register depending on the light, and the fifteen brilliant-cut diamond hour markers — 0.057 carats in total — are arranged to read as part of the dial rather than decoration applied to it. At 30mm across and 8.3mm deep, this sits close to the wrist without bulk, and the half-moon bracelet links are cut to follow smaller wrists rather than lying flat against them. The folding clasp opens with a single push-piece, which makes daily fastening straightforward without requiring two hands and a thumbnail. The L257 calibre carries one practical feature worth knowing: when the battery runs low, the seconds hand shifts to four-second jumps rather than its usual one-second beat, giving clear advance notice before the watch stops entirely.

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?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
What size strap does it take?
7mm. 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 37mm, 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.
