Singer Chris Brown spotted wearing a Purnell

During a headline performance in London, Chris Brown stepped on stage wearing one of the rarest and most mechanically complex wristwatches currently in production: the Purnell Escape II Primo Tourbillon in 18K rose gold, set with 304 brilliant-cut diamonds and 12 baguette-cut rainbow sapphires marking the hours. Limited to a strict edition of eight pieces globally, this watch represents Geneva-based independent manufacture Purnell at its most technically and aesthetically ambitious.

Founded by Eric Loth and Burak Doğançay, Purnell built its reputation almost entirely around the Escape II, which debuted to significant industry attention for its proprietary Tri-Axial Flying Tourbillon. Unlike conventional single-axis tourbillons designed to counteract gravity's effect on the escapement, the Escape II's cage rotates simultaneously on three independent axes — completing rotations in 8, 16, and 30 seconds respectively. The movement, calibre P01, beats at 21,600 vph and is constructed in-house, with the open architecture of the dial allowing an unobstructed view of the kinetic sculpture below. The blue-titanium tourbillon cage visible at 6 o'clock is particularly striking against the rose gold case.

The rainbow sapphire baguette hour markers are not merely decorative. Each stone is individually selected and hand-set to produce a precise chromatic gradient across the dial — a process that adds weeks to the production timeline and contributes substantially to the watch's six-figure price point. The 304 brilliant-cut diamonds pavé the bezel and case flanks, adding approximately 3.5 carats of VS-clarity stones to an already extraordinary package.

For collectors, the Purnell Escape II Primo occupies a rarefied tier occupied by MB&F, Richard Mille, and Greubel Forsey — independent maisons where mechanical invention is the primary value proposition. With only eight examples of this specific configuration in existence, secondary market liquidity is essentially theoretical; pieces trade privately when they trade at all.

Chris Brown has demonstrated consistent appetite for ultra-limited independent watchmaking, regularly appearing with pieces from Richard Mille and Audemars Piguet. Choosing the Purnell Escape II Primo for a live stage appearance, rather than a red carpet, signals genuine enthusiasm for the object rather than mere brand signalling. At a list price of £355,360 (approximately $427,670), it is among the most valuable watches ever documented on stage.
