Hublot Big Bang Tourbillon

About this reference

The Hublot Big Bang Tourbillon 305, specifically the reference 305.PX.0009.GR or its ceramic counterparts, was introduced around 2007 as part of the brand’s early push into high-complication watchmaking. Collectors target this reference for the HUB 1000B caliber, a manual-wind manufacture movement featuring a five-day power reserve and a prominent tourbillon carriage at the six o'clock position. The case construction utilizes the signature "sandwich" design, often pairing a 44mm platinum or black ceramic chassis with a carbon fiber or matte dial. This model represents the era when Hublot transitioned from a design-focused brand to a serious manufacture. On the secondary market, these pieces typically trade in the $40,000 to $65,000 range depending on case material and condition. A notable production detail is the limited nature of the platinum editions, which were produced in significantly smaller quantities than the standard gold or ceramic variants.
