Stepping up in the same colour and case shape
The Conquest line has run since 1954, built around the idea that a watch could be genuinely capable without shedding the restraint that Longines has always valued. This 41mm example sits squarely in that tradition: the case is slim enough at 10.9mm to disappear under a cuff, and the screw-in crown and triple-safety clasp reflect a watch that takes its 100-metre rating seriously rather than wearing it as a badge. The sunray green dial is the decision that separates it from its siblings. The finish shifts between olive and emerald as the light moves across it, with applied silver batons catching sharply against that ground. At the centre of it is the L888 calibre, whose silicon balance-spring gives it meaningful resistance to magnetic fields — a practical advantage for everyday wear — and a 72-hour reserve that comfortably clears a long weekend unworn. The display caseback lets that movement be seen, and at 133.8g on the steel bracelet the watch sits with enough presence to feel considered without becoming heavy across 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 100m it is rated for swimming and snorkelling, though not for diving.
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.
Is it a men's or women's watch?
Listed as men's.
