The company behind the design-led, diamond-growth technology used to create the 2.5 carat diamond crown of the Tag Heuer Carrera Plasma Tourbillon Nanograph.

The Tag Heuer emblem floating within the crown is a nice touch. The process employed by Capsoul to create this crown for Tag Heuer also enables them to inlay other colours of diamond, including black diamond, directly within the the lattice of perfectly clear diamond (and vice versa) allowing for incredibly diverse outcomes that are crafted from 100% pure diamond.

While synthetic diamond has been around for over half a century, it seems we're finally approaching the scale that would render the mass production of diamond crystals to protect the dial of a watch viable. Scratch-resistant sapphire crystals seemed like science fiction when Rolex first debuted one with the unveiling of the the Oysterquartz in 1970. Now they're ubiquitous in the realm of mechanical watches. I'm excited to see who will be the first to market with a truly scratch-proof crystal, machined entirely from a single piece of monocrystalline diamond.
