Longines Conquest Stainless Steel Automatic 42mm Mens Watch
Ref. L38354026
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 271 Longines watches in stock.The Conquest was reborn in 2023 with a more purposeful silhouette, and this chronograph sits at the sporting end of that updated range. The visual anchor is the panda-style dial — a matt silver field against dark green sub-counters — and the fixed bezel is green ceramic, hard enough to take daily knocks without marking. The L898.5 calibre inside is a modular chronograph with a silicon balance spring, which keeps it stable against magnetism and temperature in a way that older lever-escape designs are not, with a 59-hour reserve generous enough to survive a long weekend off the wrist. At 50.2mm lug to lug and 169 grams, this wears large and announces itself — the ergonomic lug curve helps it settle on the wrist rather than rock, but a smaller wrist will find it a demanding fit. The H-link bracelet adjusts by friction pins, which is fiddly to change but holds its position reliably once set, and the triple-safety clasp requires deliberate effort to release, which on a watch this substantial feels like the right trade.

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.
What size strap does it take?
22mm. 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 50.2mm, which suits wrists from roughly 17.5cm (7 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.
