Longines Conquest Chronograph 42mm Mens Watch Black
Ref. L38354526
Sits in Longines’s upper tier here — more premium than three quarters of the Longines watches we list, which start at £900.
Price range £900 to £22,850 across 254 Longines watches in stock.The Conquest name dates to 1954, and this chronograph sits at the more purposeful end of what that line has become — a tool-oriented case with a fixed ceramic bezel and a screw-in crown, built around an in-house movement with a 59-hour reserve and a column-wheel chronograph layout reading across three subdials. The L898 runs at 28,800 vibrations per hour, which is fast enough to time to the nearest eighth of a second, and at 42mm the case is wide enough to make the three-register dial legible without crowding. The black circular-brushed dial keeps the silver counters from looking decorative; at an angle, the texture gives the face some depth without complicating the read. At 14.30mm it is not especially slim — this wears as a sports watch, not a dress piece — but the triple-safety clasp and the overall weight of 172g confirm that the bracelet is doing real work rather than just filling the gap between case and wrist. The sapphire caseback is worth a few seconds when the watch is new: the L898 is a tidy movement, and Longines finishes it to a standard that rewards the look.

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 59 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
Is it a men's or women's watch?
Listed as men's.
