Hublot builds on its expertise wielding the coloured sapphire-equivalent of SAXEM, following up on yellow and emerald with now in 2024, green. While as resistant as sapphire, SAXEM has a different shine: a brighter one. Its structure has fewer strains, it is more uniform and seamless.

The Green SAXEM of the new Big Bang UNICO highlights a number of the innovations by Hublot. The 42 mm case is solid and robust. It packs all the power of SAXEM into a dense, compact diameter. The material does not receive light, but creates the illusion of emitting it.

The Green SAXEM is diffused into the smallest contours of the case and bezel, which are studded with six of Hublot’s iconic titanium H-shaped screws. The One Click system patented by Hublot for its interchangeable straps can be found at 12 and 6 o’clock.

For the movement, Hublot has opted for another Manufacture design: the UNICO 2 calibre, a new- generation flyback chronograph, the HUB1280. This is a first as the micro-rotor HUB6035 powered the previous Big Bang SAXEM. The movement is still self-winding, but now offers collectors the added benefit of a high-performance tungsten oscillating weight, visible through the back of the Green SAXEM case.

Combining advanced technology and a robust design, the HUB1280 calibre features the iconic column wheel at 6 o’clock, UNICO’s technical and aesthetic signature. Another distinctive aspect is the date disc, entirely visible around the movement, with the aperture set in the centre of the 60-minute counter at 3 o’clock.

The movement is finished in black PVD, as are the crown and its two push-pieces. For the index and the hands’ luminescent material, Hublot has successfully reproduced the exact shade of Green SAXEM. This is a first, and will remain highly exclusive as only 100 Big Bang Green SAXEM watches will be produced.
