he Openworked Tourbillon Ultra-Violet invites the imagination to enter a metaverse city of futuristic architecture illuminated by rays of light and fluorescent colours. Among the vibrant, bright tones, the choice of ultra-violet makes the dial’s grid of this latest creation stand out. This specific, mysterious and fascinating shade surrounds and highlights the main components of the movement, such as the flying tourbillon, the off-centre micro-rotor, the power reserve indicator and the barrel, which stand out against the rhodium-plated and microbeaded black plate.

The satin-brushed and rhodium-plated dial of the Openworked Tourbillon Ultra-Violet is multilayered, with carved microbeaded pockets which create a refined grid, with microbeaded profiles angled at 45° in a vibrant ultra-violet hue obtained through positive PVD coating. Limited production of only 5 pieces with a 42mm case and an additional 4 pieces measuring 38mm in diameter.

The Piccadilly case is crafted from grade 5 titanium. Its flat, horizontally brushed case band, recessed in relation to the polished, domed bezel and case back, gives it a sober, modern aesthetic that is immediately reminiscent of Speake Marin. The flared, grooved crown and the geometric lugs, which hold the strap attachment bars, secured by two screws, complete the harmonious appearance.

The SMA05 calibre is part of the collection of mechanical movements developed in-house by Le Cercle des Horlogers, the Manufacture of Speake Marin. Automatically wound, it operates at a frequency of 3Hz (21,600 vibrations per hour) and offers a 72-hour power reserve from a single barrel. It is distinguished by its tourbillon mechanism at 1.30: an unusual position that stands out as unique in the watchmaking panorama due to the difficulties of accommodating the time-setting module and now a distinctive and recognised feature of the Maison.

Available in 38mm and 42mm cases, the timepiece is complemented by a black rubber strap fastened to the wrist with a titanium pin buckle.

Price: CHF 69,400 (38mm), CHF 69,900 (42mm) excl. taxes
