Audemars Piguet Royal Oak Chronograph 39mm Stainless Steel
Ref. 25860ST.OO.1110ST.05
Few watches carry a collector nickname as specific as "Kasparov," and fewer still earn it. This reference is credited with introducing the Grande Tapisserie texture to the Royal Oak dial — the fine hobnail guillochage that has since become inseparable from the line's identity. That alone would secure its place in the catalogue, but the movement beneath the caseback is what sustains serious interest: the Calibre 2385 draws on the Frédéric Piguet 1185 architecture, a column-wheel and vertical-clutch design that produces a chronograph start with no hand-jump and no drag on the mechanism. At 39mm and 11mm deep, the proportions are genuinely unusual for a chronograph — most movements adding a column wheel and vertical clutch to a case also add bulk. This one does not, and the integrated bracelet that tapers from the wide lugs pulls it flat against the wrist in a way that reads as a sports watch without behaving like one under a cuff. Genta's brushed flanks against the polished bevels on the octagonal bezel, and white-gold hands and indices against the white dial, give the three sub-dials at three, six and nine a monochromatic restraint that the case construction keeps from tipping into quietness.

Learn more about Audemars Piguet
Jules Louis Audemars and Edward Auguste Piguet, both from the Vallée de Joux, formalised their partnership in 1875. The valley was then the centre of complicated movement work, and the pair spent their early decades supplying calibres to other houses — Tiffany among them — rather than selling under their own name.
The firm remains privately held by descendants of the founding families, an unusual survival in an industry consolidated into three or four groups.
Its defining moment came in 1972, in the depths of the quartz crisis, when Audemars Piguet released the Royal Oak: a steel watch priced above gold ones, with an octagonal bezel, exposed screws, and an integrated bracelet, drawn by Gérald Genta reportedly overnight. It was widely mocked at launch. It created the luxury sports watch category and now underpins the entire company.
The Royal Oak Offshore of 1993 pushed the same design larger and louder, and drew similar early scepticism before becoming a pillar in its own right. The Code 11.59 collection, introduced in 2019, was the house's attempt to prove it could sell something else — a mixed reception commercially, though the movements inside are serious.
Underneath the modern noise, the complication pedigree is intact: minute repeaters, perpetual calendars, and some of the thinnest tourbillon movements built anywhere.

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.
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 40 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
26mm. 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 39mm it sits in the range that suits anyone.
