Stepping up in Speake-Marin's range
Peter Speake-Marin built his reputation on finishing movements to a standard that made them worth looking at, and the One & Two Openworked makes that the entire point of wearing the watch. The SMA01 running beneath the dial is COSC-certified and beats at 28,800vph through 33 jewels, wound by a fully integrated micro-rotor that keeps the caseback as clean as the front — both sides covered in anti-reflective sapphire so the movement is readable from either end. Engraved onto the visible mainspring barrel are words from the brand's own philosophy, "RESPECT" and "CREATIVITE" among them, legible only once you have looked closely enough to find them. The Piccadilly case — named for the London street that informs Speake-Marin's identity — carries all of this in 18K red gold at 10.5mm thick, which for an openworked piece in a precious metal is genuinely restrained. The heart-shaped hands, polished and black PVD-coated, and the 3D small-seconds counter set at 1:30 rather than the conventional 6 o'clock give the dial an asymmetric logic that takes a moment to read, and rewards that moment. On a grey grained leather strap with a matching red gold pin buckle, it sits as a considered object rather than a conspicuous one.

Learn more about Speake-Marin
Peter Speake-Marin trained at Hackney Technical College in London, spent years restoring antique watches on Piccadilly and later worked at Renaud et Papi, the complications workshop behind much of the industry's most difficult work. He founded his own brand in Switzerland in 2002.
The house style was established early and has stayed: the Piccadilly case with its distinctive stepped bezel, the topping tool motif taken from a watchmaker's own bench, and heart-shaped bridges visible through the back.
Christelle Rosnoblet bought the company in 2012 and built a movement workshop in the Neuchâtel region, moving it from assembling supplied calibres towards developing and finishing its own.
The output is deliberately small and deliberately difficult — tourbillons, minute repeaters, the Vertical Double Tourbillon, and an Art Series with hand-sculpted dials. These are watches made in dozens rather than thousands.
Peter Speake-Marin himself has since moved on to other projects; the brand he named continues in Geneva.

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 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 52 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 men's.
Has the price changed recently?
It's currently at its lowest recorded price since we began tracking it. It's ranged between £25,650 and £42,725, today it's £25,650.
