The World Time complication at Patek Philippe traces back to Louis Cottier, the Geneva watchmaker who devised the mechanism in the 1930s, and the 5131 is its present form — the successor to the 5130, launched at Baselworld 2017. What separates this platinum iteration from any other reference in the line is its dial, which is not printed or lacquered but built: cloisonné enamel, the world mapped from the North Pole outward, constructed by soldering fine gold wires into place and firing the piece through multiple oven stages to build up the colour in layers. Only a handful of artists within the manufacture can execute it, and the process means every example emerges slightly differently. The 240 HU driving it is among the thinnest automatic world-time movements made, which is why the case sits at 10.6mm — genuinely flat for something carrying a complication of this reach, and the reason it disappears beneath a cuff in a way a conventional dress-complications case will not. The 22-carat gold micro-rotor and silicon Spiromax balance spring are engineering choices that have nothing to do with aesthetics and everything to do with rate stability over the 48-hour reserve. At 241.8 grams on the wrist, the integrated brick-link bracelet makes its presence felt immediately — this is a dense, serious object, and it wears that way. The brand names are engraved directly into the bezel rather than printed on the dial, a detail that reads as restraint until you look closely enough to notice it.

Learn more about Patek Philippe

Antoine Norbert de Patek, a Polish cavalry officer exiled after the November Uprising, founded a watch business in Geneva in 1839 with his countryman François Czapek. The partnership dissolved after six years, and in 1845 Patek took on the French watchmaker Adrien Philippe, inventor of the keyless winding crown. The firm became Patek Philippe in 1851.

That single invention mattered more than any other in the company's early history: it removed the winding key, and every modern watch descends from it. Queen Victoria bought a Patek pendant watch at the Great Exhibition the same year, establishing the royal patronage the house has traded on ever since.

The Stern family, dial manufacturers and long-standing suppliers, bought the company in 1932 during the Depression. Four generations later it remains in their hands — the last independent family-owned manufacture in Geneva, currently led by Thierry Stern.

Patek's reputation rests on complications: the Calibre 89 of 1989 carried thirty-three of them, and the Grandmaster Chime remains among the most complicated wristwatches made. The Nautilus, drawn by Gérald Genta in 1976 as a steel luxury sports watch, became an unlikely commercial phenomenon four decades after launch.

Production stays deliberately modest, in the tens of thousands annually, and every watch carries the Patek Philippe Seal, an in-house standard the company adopted in 2009 after abandoning the Geneva Seal as insufficiently strict.

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.

Water resistance explained

Will the glass scratch?

Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.

Sapphire, mineral and acrylic compared

Does 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 compared

How long does it run for when it's not worn?

About 48 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 48.5mm, which suits wrists from roughly 16.5cm (6½ inches) upward.

Lug-to-lug decides fit more than case diameter does.

How to size a watch to your wrist

Is it a men's or women's watch?

Listed as unisex, and at this size it suits any wrist that takes the dimensions.
