Longines Conquest 42mm Mens Watch Blue Rubber Strap
Ref. L38354989
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 the chronograph has long been its most technically ambitious expression — the configuration that best justifies the collection's claim to sporting precision. This version pairs the calibre L898 with a silicon balance-spring, which gives it genuine magnetic resistance without the thickness penalty that antimagnetic shielding usually demands. The movement runs at 28,800 vibrations per hour and carries a 59-hour reserve, enough to sit out a long weekend without winding. At 42mm the watch reads large but wears as a sports chronograph should: the blue ceramic bezel with tachymetre scale, silver matt dial and contrasting blue sub-dials at three, six and nine are designed to be read quickly, and the anti-reflective sapphire on both sides keeps them readable across most lighting conditions. The blue rubber strap coordinates with the dial registers rather than just sitting beside them, and the double-security folding clasp with micro-adjustment means the fit can be dialled in without tools as a wrist changes through the day. The exhibition caseback is worth noting — the L898 is Longines' own calibre and the finishing justifies the view.

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.
