Presented during LVMH Watch Week in January 2023 Singapore, the new Hublot Big Bang Rainbow Editions reveals the art of bejewelled case setting. They are adorned with an array of gemstones in a perfect gradation of colours, seamlessly running through all the shades of the rainbow.
Two models are available with rainbow setting: a 42mm Big Bang Integrated Chronograph and a 40mm Big Bang Big Bang Integrated Time Only watch.
These sparkling timepieces are fully paved from the case to the bezel to the bracelet. Precious stones take their place alongside the most stunning minerals: ruby, amethyst, blue topaz, tsavorite, as well as a whole spectrum of sapphires – pink, orange, blue and yellow.

Chronograph & Time Only King Gold Rainbow Models
There are 174 gemstones in total for the Big Bang Integrated Chronograph model and 176 gemstones for the Time Only, and the bracelet for each piece features 768 and 748 set gemstones respectively.

The case and bracelet are made of King Gold, a proprietary alloy that offers a warmer colour than traditional 18K 5N gold. Containing platinum, it lends itself perfectly to all the polishing and satin-finishing operations used to full effect on these two variations, alternating flat satin-finished surfaces and polished chamfers whose brilliance sparkles in harmony with each of the gemstones set on the piece.
Finally, the two pieces share the same completely black sapphire dial: main plate, flange and date window. Its monochrome backdrop showcases the full radiance of the rainbow setting.
Two large skeleton hands display the hours and minutes. The crown and pushers (chronograph model) are made of King gold. The black rubber protective structures form two “ears” at either side at 3 o’clock and 9 o’clock.
The Big Bang Integrated Chronograph Rainbow model is equipped with the Unico Manufacture self-winding movement. Developed by the Hublot Manufacture, this mechanical skeleton calibre offers a power reserve of three full days.

The Big Bang Rainbow Time Only watch has a 40-mm diameter case with a thickness of just 9.25 mm. This model houses the MHUB1710 Self-winding movement with three hands and date display. It has a power reserve of 50 hours.
The case and bracelet are seamlessly blended in style, material and colour all while offering complete comfort to the wearer.
