As we noted last year, although Hublot are not the only brand to have released sapphire-cased watches, they are the brand that has become known for the industrialised manufacture of such cases, starting with transparent ones that were followed by ones in a range of colours and also introducing cases made from their trademarked alloy SAXEM (Sapphire Aluminium oXide and rare Earth Mineral), which is a mixture of aluminium oxide (the building block of synthetic sapphire) with rare earth minerals such as thulium, holmium and chromium.
You may recall that in their LVMH Watch Week last year, they launched the Big Bang Tourbillon Automatic Orange Sapphire, the first sapphire case in this colour. This year, a new colour has been brought into the mix, with the vivid new Big Bang Tourbillon Automatic Purple Sapphire, the first time such a colour has appeared, again in a translucent form, in a sapphire watch case.
The 44 mm purple polished sapphire case has a thickness of 14.5mm and water resistance of 30m. This new colour is a composite made of Al₂O₃ (aluminium oxide) and chrome. The translucent bezel has the classic six H-shaped titanium screws.
The movement is, again, the automatic Calibre HUB6035 Manufacture, which beats at 21,600 VPH and has a power reserve of three days. It has a micro-rotor which you can see at 12 o’clock, and a skeletonised tourbillon at 6 o’clock. There are three sapphire bridges, which you can see on the dial side, and a sand-blasted plate.
The matching transparent purple rubber strap has Hublot’s One Click system and a titanium folding deployant clasp. For those who have never tried on one of Hublot’s sapphire watches, they are, as expected, very light on the wrist.
Coming in a limited edition of fifty pieces, the RRP is AUD 279,000/ CHF 190,000/ EUR 198,000.
