Forged Carbon Chronograph — Rainbow Bezel, White Pavé Dial

The bezel is what people see first. It is a single ring of baguette-cut coloured gemstones, laid side by side in polished steel with nothing printed on it and no gap anywhere.

The colours move the way light does through a prism: red at twelve, orange, yellow at three, green, blue at six, then violet and magenta, and round to red again. The steel setting keeps every colour cool and clear, where gold would warm it.

Underneath, the case is one-piece carbon fibre, black with a fine silver-grey swirl running through the material. The crown and both pushers are black, so the only colour on the outside of the watch is the ring of stones.

The dial is white, paved edge to edge with small stones of high-clarity moissanite. There is no minute track and no printing round the edge: the stones run straight up to the steel rim, so the whole face catches the light at once.

Eleven of the hours are single coloured gemstones in slim settings, following the bezel's rainbow, orange near the top through yellow, green and blue to violet and fuchsia. A small steel plaque sits under twelve. The three counters have a grey texture like cut meteorite, ringed in steel with black print, and the polished hands carry white lume.
