Longines Conquest Chronograph 42mm Mens Watch Silver
Ref. L38354726
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 sportier end of what that lineage now covers — a proper timed-event watch rather than a dressed-up three-hander. The panda layout is the telling choice: matte silver ground, black sub-dials at three, six and nine, a tachymeter scaled on the ceramic bezel rather than printed on the dial. It is a configuration that has been used on serious chronographs for the better part of a century, and Longines has applied it without softening it for a broader audience. At 42mm the proportions are conventional for the category, but 14.30mm of thickness is honest rather than flattering — this is a chunky piece that wears accordingly, and the 50mm lug-to-lug span means it will demand a larger wrist to sit properly. The L898 running inside is worth noting: 28,800 beats per hour and a 59-hour reserve means a watch left on Friday night will still be running Monday morning, which matters more than it sounds for a chronograph that will be started and stopped rather than simply worn. The exhibition caseback is a quiet reminder that the movement is presentable enough to show.

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.
Will it fit my wrist?
Lug-to-lug is 50mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's.
