Description

What if MB&F created an elegant 38mm watch?

The MB&F SP One, initially dubbed "Three Circles", showcases a trinity of floating elements – the barrel, balance wheel, and dial – defying gravity on your wrist. These components appear to hover mysteriously at the centre of an amphitheatre, all visible through invisible sapphire domes, with the balance wheel performing a mid-air dance and the tilted dial highlighting MB&F’s clever conical gearing.

Encased in a 38mm pebble-like shell, the SP One melds a smooth, tactile feel with a bezel-free design and delicately detached lugs. As MB&F’s slimmest and smallest watch, it nonetheless remains true to the brand’s signature three-dimensional architecture and boundary-pushing spirit. Somewhere between MB&F’s radical Horological Machines and more classic Legacy Machines, the SP One inaugurates a new, undefinable “Special Projects” collection.

The SP One movement is crafted around the three key elements of any mechanical watch: the barrel, the balance wheel, and the dial. Each component isn’t just there for show; they’re meant to feel like they’re floating in mid-air. It’s the thoughtful architecture of the movement that truly enhances this captivating levitation effect: most components are cleverly hidden beneath the three key elements, letting their beauty take centre stage.

Visually, the three elements have identical circumferences, adding complexity to the movement's design. The single-barrel architecture is elegantly suspended, enhancing the levitation effect and presenting a genuine challenge for the movement designers. The balance wheel oscillates at 2 o’clock and captivates the wearer's eyes like a flying saucer. The dial is tilted just right to highlight MB&F's expertise in conical gearing.

Surrounding this movement is the “amphitheatre”: a bevelled flange that spotlights the intricacies of the movement.

Flip the SP One over, and you'll uncover the hand finishing and overall attention to detail typical of MB&F. The wheels are hand-angled, with prominent chatons, and the finish balance is subtle between satin, polished, and micro-blasted surfaces.

In essence, a classical MB&F that has nothing classical about it.
