About this reference
The Hublot Big Bang Unico Chronograph Rainbow 45mm (Reference 411.OX.9910.LR.0999) was introduced in 2017 and remains a part of the brand’s high-jewelry catalog. Collectors target this reference for its 18k King Gold case, a proprietary alloy containing platinum, which is set with 176 colored gemstones including rubies, pink sapphires, amethysts, blue sapphires, blue topazes, tsavorites, and yellow and orange sapphires. The bezel features an additional 48 baguette-cut stones in a gradient pattern. It utilizes the in-house Caliber HUB1242 Unico movement, an automatic flyback chronograph with a 72-hour power reserve and a visible column wheel on the dial side. On the secondary market, this model typically commands prices between $65,000 and $85,000 depending on condition and completeness. A notable production detail is the "One Click" strap system, allowing for rapid changes between the multicolored alligator leather and rubber straps provided with the watch.
