Longines Conquest Heritage 40mm Mens Watch Black
Ref. L16504526
Sits in Longines’s upper tier here — more premium than three quarters of the Longines watches we list, which start at £1,050.
Price range £1,050 to £22,850 across 113 Longines watches in stock.The Conquest name goes back to 1954, when Longines built it as a sports watch around movements precise enough to time international athletics. This Heritage edition retrieves the proportions and detailing of that original generation — the black lacquer dial, the applied rose gold-toned indexes — and updates the engineering beneath them. The calibre L888 carries a silicon balance-spring, which removes the need to worry about magnetic fields from phones or laptop bags, and winds itself to a 72-hour reserve, enough to survive a long weekend without being worn. At 40mm and just 10.8mm thick it sits closer to a dress watch than most sport-heritage pieces of this size, and the polished case helps it read that way under a jacket. The dial in direct light has a depth that black lacquer gives and printed dials do not; the rose gold hands and indexes sit clearly against it without the contrast feeling harsh. Flip it over and the exhibition caseback shows an 18-karat gold medallion engraved with a fish — a small, unhurried detail that has no audience except the owner.

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.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
How 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.
What size strap does it take?
20mm. 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.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
Cheapest place to buy
Goldsmiths is the only UK retailer we track stocking this reference, so there is nothing to compare it against today.
Who are Goldsmiths?
Goldsmiths has been selling watches in Britain since 1778 and is part of the Watches of Switzerland Group, which is listed on the London Stock Exchange. They are an authorised dealer, so a watch comes with the manufacturer’s own warranty.
