Jacob & Co. has never treated high watchmaking as a quiet discipline, and the Brilliant Flying Tourbillon Baguette Pastel Arlequino is a vivid reminder of that instinct.
This unique piece combines a fully gem-set white-gold case, a pastel sapphire mosaic dial and a flying tourbillon, but its real provocation is hidden in plain sight.
The balance wheel itself is set with diamonds, placing high jewellery on one of the movement’s most sensitive regulating components.
At a glance
- Jacob & Co. has introduced the Brilliant Flying Tourbillon Baguette Pastel Arlequino as a unique high-jewellery tourbillon watch.
- The watch features 54 brilliant-cut diamonds set directly onto the balance wheel of its self-winding flying tourbillon movement.
- It is a one-of-one creation in 18K white gold, with pricing available upon request.
A pastel Arlequino case with serious stone-setting
The 42mm case is made from 18K white gold and measures 11.61mm thick, keeping the proportions relatively restrained for such an elaborate jewellery watch.
Its surface is invisibly set with 194 baguette-cut pastel sapphires and 32 baguette-cut white diamonds, creating a crisp, geometric skin of colour and light.
The crown continues the treatment with 12 sapphires and a single white diamond, while a sapphire crystal with anti-reflective treatment sits over the dial.
Water resistance is rated to 30 metres, which is entirely in keeping with a high-jewellery tourbillon intended for careful wear rather than aquatic adventure.
The dial carries the Arlequino theme further, using 139 baguette-cut pastel sapphires and 23 white diamonds in a bright arrangement of green, blue, lavender and pink.
The inspiration is the costume of Arlecchino from Italian commedia dell’arte, though the execution feels more architectural than theatrical.
Rhodium leaf-shaped hands provide the hours and minutes without disturbing the gemstone composition too much.
The balance wheel becomes the spectacle
The flying tourbillon sits above 6 o’clock and rotates once per minute, giving the dial its mechanical centre of gravity.
What separates this watch from a conventional jewellery tourbillon is the treatment of the balance wheel inside that rotating cage.
Jacob & Co. has set 54 brilliant-cut white diamonds directly onto the balance wheel, turning the oscillating heart of the watch into a moving ring of reflected light.
At 21,600 vibrations per hour, the balance is constantly shifting, while the tourbillon’s one-minute rotation changes how those stones meet the eye.
The visual effect is less like static gem-setting and more like a halo that never quite repeats itself.
Technically, this is the kind of detail that can’t be treated casually.
The balance wheel governs the rate of the watch, and adding stones can alter mass, poise and weight distribution if the work isn’t carefully managed.
Jacob & Co. says the required characteristics of the balance wheel have been preserved despite the integration of the diamonds.
A self-winding calibre with diamonds on both sides
The watch is powered by the self-winding Jacob & Co. calibre JCFA02, a micro-rotor movement with a flying tourbillon.
It measures 30.4mm wide and 6.9mm thick, and it is built from 184 components with 27 jewels.
The power reserve is 72 hours, a useful figure for a watch that may spend time between appearances rather than being worn every day.
The gem-setting continues through the back of the movement, where the bridges are set with 234 brilliant-cut white diamonds.
That decision matters because it makes the watch feel complete from both sides, rather than treating the caseback as a secondary view.
The Brilliant Flying Tourbillon Baguette Pastel Arlequino is worn on an alligator strap with an 18K white-gold tang buckle set with 21 baguette-cut pastel Arlequino sapphires.

For collectors drawn to Jacob & Co.’s most expressive work, this is less a discreet tourbillon than a technical jewellery statement with genuine watchmaking tension at its centre.
The diamond-set balance wheel is the kind of flourish that only makes sense when audacity and precision are allowed to occupy the same space.
