Introducing the Hublot Big Bang Tourbillon Automatic Green Saxem

Since its founding in 1980, Hublot has established itself as an industry leader in materials and composites. As an independent and vertically integrated manufacture, the brand has been able to focus on what it does best: exotic complications and exotic materials. In the last few years Hublot has been using its material engineering ability again and again to bring out Saxem- a sapphire-like material unique to the brand. Last year Hublot added green to the repertoire and it’s great to see it back again…

The Juice:

The Big Bang is one of Hublot’s main collections. Created in 2005, it was designed to showcase all of the fruits of Hublot’s pioneering. It is the testing ground for all many of their newest innovations, before they make it into the other collection. The collection is home to a range of materials, includings Saxem, and complications such as the tourbillon, the flyback chronograph, and as of 2025 a 10-day power-reserve.

The case is the only place to really start on this watch. You simply cannot escape the flashy and vibrant tones of the translucent Green Saxem case. The material retaining both the hard-wearing, resistant, and scratch-proof characteristics of Sapphire (despite being different on a molecular level) and the classic lines of Hublot design, which is a feat in itself given how difficult it is to work with. Having tested sapphire cases on a couple of occasions, this watch will have a fabulous heft to it, something that is massively overlooked when talking about sapphire-like watches.

The dial is the perfect combination of legibility and transparency. It might be a little off-putting to have a completely opaque dial on a watch that is otherwise compeltely translucent. Some watches with this sort of semi skeletonized/transparent dials struggle with legibility, as poorly defined indices and crowding render it almost impossible to read. Thankfully, Hublot are professionals when it comes to this and making a dial with two functions is just a walk in the park for them. Equally, this type of dial really helps draw the focus to the star of the show: the green saxem case.

The movement powering this beast is the Manufacture Calibre MHUB6035 and it’s very impressive for a variety of reasons. Number one, it’s an automatic tourbillon- an incredibly difficult complication to execute properly and beautifully. Number two, it’s got a micro-rotor that powers the winding. Number two (B) the micro-rotor is actually on the dial-side, nestled beneath the twelve o’clock position. Made from 22 carat gold to ensure that it has enough momentum, the rotor itself has actually been coloured black so as not to interfere with the rest of the design: Hublot know what’s important here. The watch comes with a 72-hour power-reserve which is more than enough for such an impressive watch.

The strap is a classic. Hublot use it time and time again to great effect: their iconic rubber strap. It was putting the rubber strap on a precious metal watch for the first time that really made them famous. Using their proprietary strap change system, names ‘One Click’, you can swap out the strap on this in an instant.

Overall, this new Hublot Big Bang Tourbillon in Green Saxem is a fabulous continuation of the brand’s development of both their proprietary materials and their constant drive to put their mark on traditional complications, we can’t wait to see what else 2025 holds for them. It is limited to 18 pieces total.
