Longines Master Collection Moophase 34mm Ladies Watch Mother Of Pearl
Ref. L24095897
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 carried Longines' mechanical complications since 2005, sitting above the rest of the range as the house's argument for traditional watchmaking in an everyday form. This version adds a moonphase and pointer date at six o'clock, both sharing the subdial with a coherence that keeps the dial readable rather than crowded. The rose gold here is not plating — an 18-karat cap over the steel case and bracelet links means the colour sits substantially thicker than surface treatments, and it will wear accordingly over years of use. Against that, the mother-of-pearl dial sets twelve Top Wesselton VS-SI diamonds at the hours, stones graded closely enough in clarity that they read as a set rather than as individual embellishments. At 34mm the watch is proportioned for a smaller wrist, though the moonphase and date modules push the thickness to 11.10mm, which is honest: complications have depth, and this one does not pretend otherwise. The L899.5 runs a silicon balance spring, which means it holds its rate through the kind of magnetic fields that quietly disorder conventional hairsprings — a practical benefit that is easy to overlook in something styled primarily as a dress watch, and worth noting.

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?
18mm. 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 women's, though at 34mm 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.
