The Unico Blue Sapphire is, in my opinion, the most attractive sapphire watch on the market.
With a 45 mm diameter round case, it’s much less crazy than some of the competing watches from Richard Mille or Bell & Ross, and considering it’s crafted from polished blue sapphire, which nobody else is using right now, makes it all the more exclusive.
Blue is vibrant and translucent yet less transparent than clear sapphire, which results in a more elegant aesthetic, and you don’t have to worry about seeing arm hair through the watch, which sapphire crystal cases (and highly skeletonized watches) tend to have a problem with.
Hublot outsourced the production of the watch case, as most watch companies do with any kind of sapphire crystal manufacturing. The case middle, bezel, and back are cut from synthetic blue sapphire crystal (that rates a 9 on the Mohs hardness scale) which is then polished. Only a few pieces of the watch case are made from titanium: the H-shaped titanium screws, the crown (which is over-molded with silicon), the pushers, and the deployant buckle.
The skeleton dial is made from transparent smoked gray resin and reveals the components of the automatic Unico in-house caliber HUB1242 movement, which has a 72-hour power reserve and features a column-wheel equipped flyback chronograph with a 60-minute counter, as well as a transparent date wheel which surrounds the perimeter of the dial.
The Hublot Big Bang Unico Blue Sapphire is water-resistant to 50 meters. Limited to 250 pieces. (Ref. 411.JX.4802.RT) Retail is $85,000.
