Stepping up in the same colour and case shape
The Conquest Heritage traces its design to Longines' 1950s Conquest line, the house's instrument watches of the postwar period. This version makes no attempt to disguise what it is drawing from: the 38mm case, the applied baton indices on the lacquered blue dial, the overall proportions — all of it reads as mid-century, and deliberately so. What sits beneath is fully contemporary: the L888 carries a silicon balance spring that shrugs off magnetic fields in a way a conventional hairspring will not, and the 72-hour power reserve means a watch left on the nightstand Friday evening is still running Monday morning. The caseback is worth turning over. A screw-down cover decorated with an 18-karat gold medallion bearing the heritage fish constellation motif is unusual on a watch at this level of understatement — it is the kind of detail most owners find for themselves rather than being shown. On the wrist, 38mm on an alligator strap wears closer to a dress watch than a sports piece, which is the honest reading of 50 metres: capable of rain and the odd splash, but this is not a watch for the pool.

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?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
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, though at 38mm it sits in the range that suits anyone.
