Gucci G-Flat watch, 36mm
Ref. YA166401
Sits in Gucci’s upper tier here — more premium than three quarters of the Gucci watches we list, which start at £499.
Price range £499 to £8,130 across 56 Gucci watches in stock.The G-Flat traces its geometry to the 1970s, when Gucci drew from the architectural language of that decade to produce a case built around octagonal angles and a pronounced multi-layered profile. That origin gives this revival something to stand on beyond fashion — the form has a logic to it, not merely a look. On the wrist, the octagonal case reads as deliberately structured against the black opaline dial, which has enough texture to shift slightly under different light. Roman numerals sit only at twelve and six, leaving the rest to baton markers, which keeps the face from feeling cluttered at 36mm — a size that works equally well on narrower or broader wrists. The butterfly deployant fastens cleanly and sits flush, so the bracelet moves as a single piece rather than announcing itself. The exhibition caseback is worth knowing about before you buy: the automatic rotor is visible through it, and on a watch with this much surface geometry, that rear view completes the picture in a way a solid caseback would not.

Learn more about Gucci
Guccio Gucci opened a leather goods shop in Florence in 1921, and the house became one of the defining Italian luxury brands of the twentieth century.
Gucci's watches occupy unusual ground. Unlike most fashion houses, Gucci produces in Switzerland through its own facility in La Chaux-de-Fonds, and the watches carry Swiss Made designation. The G-Timeless line uses Swiss quartz and automatic movements, and recent references have included in-house-adjacent complications.
The design language is unmistakably Gucci — the green-red-green web stripe, the interlocking Gs, bee and snake motifs — applied to cases that are generally well proportioned. It sits above the licensed-fashion category without claiming to compete with the Swiss manufactures.

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 50 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
Is it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
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.
