This is a little crazy looking for me, but hey, I’m sure there are many folks out there willing to shell out $16,500USD (15,000CHF) for an iridescent watch. Nothing like taking what is already a pretty funky looking watch, and making it funkier!

From Graham:
The multitude of colours is hypnotic. The iridescence of the Swordfish Booster Iris, similar to the most beautiful natural wonders, is eye-catching. Do you know what Iris means in Latin?

Rainbow.

This rainbow effect is not due to pigment but interferences of light. It means that light waves interfere with one another on a surface refracting parts of the spectrum which create the iridescent colors. You have probably already seen it in a soap bubble or in an oil stain on a wet pavement but it results from a high-technological process.

The change of colours is also due to the extremely complex composition of the layers’ oxide. The steel case and components have been placed in big vacuums producing plasma reaction.

This unique coating contains multi-layered structures that provide thin-film interference. The thickness across the surface causes changes of colours in reflected light. Iridescence adds a new dimension to “surface”.
