Longines Master Collection Stainless Steel and 18ct Yellow gold 40mm Mens Watch Silver
Ref. L27935727
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 231 Longines watches in stock.The Master Collection has always occupied a specific position in the Longines catalogue: classical dress proportions with a movement specification that most competitors at this level cannot match. The L888 runs on a silicon balance spring, which makes it effectively immune to magnetic interference and considerably more stable over time than a conventional hairspring — and three days of power reserve means it will still be running on a Monday morning after a weekend off the wrist. At 9.4mm thick, a 40mm watch sits closer to a slim dress reference than anything designed to be noticed, which is exactly where the ivory dial and gilt leaf hands want to be. The two-tone construction is handled with restraint: 18ct yellow gold is used on the bezel and the inner bracelet links rather than as an overlay across the whole case, so the effect reads as considered rather than heavy. The folding clasp uses a dual push-piece release and sizes through conventional link removal — the 21mm lug width means a replacement strap is easy to source if the bracelet is not to taste.

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?
No. At 30m it will survive rain and handwashing, but not submersion of any kind.
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?
21mm. 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.
