Replica Hublot Big Bang Unico Sapphire Rainbow, like the rest of Hublot’s sapphire-cased watches, it’s housed in a 45mm Big Bang case, crafted from ice-like sapphire, with a composite resin dial which allows a clear view of the HUB1242 flyback chrono movement.
So far, so sapphire. The bezel, though, is something else entirely. The base is 18k white gold, and it’s set with 48 baguette cut stones – sapphires, rubies, topazes and tsavorites – in all the colours of the, well, rainbow. These stones are beautifully graded, ranging from vivid pink through to arctic blue all the way up to fiery orange.
The replica Hublot Big Bang Unico Sapphire Rainbow feature bezels set with 48 amethysts and sapphires. With a nice gradient between the 48 stones —but nowhere near to the gradient achieved by Rolex for their Rainbow Daytona—, the color of the stones goes all the way from purple to red in a gradient that includes shades of light blue, violet and bright pink in between.
The case middle and back of the new Big Bang Unico Sapphire Galaxy is cut from blocks of sapphire, a material which is almost as hard and scratch-resistant as a diamond —9 on the Mohs scale as opposed to 10 for diamond. The only parts of the watch that are not made of sapphire are the bezel set up as well as the crown and pushers which are made of titanium.
