About 45mm Watches
The 45mm case size emerged as a defining statement in the early 2000s when the luxury watch industry embraced oversized sport cases influenced by independent and avant-garde brands, and Hublot's Big Bang line became one of its most celebrated expressions. Introduced in 2005, the Big Bang brought together rubber straps, a multi-layered bezel construction, and an integrated case architecture that made 45mm feel purposeful rather than purely large. The Unico variant adds Hublot's in-house flyback chronograph movement, elevating these references from bold accessories to serious complications. Across titanium, black ceramic, red ceramic, King Gold, and transparent sapphire crystal cases, the 45mm Big Bang Unico demonstrates how a single case size can support an enormous range of finishes, materials, and collector-focused limited editions.
What to Look For
Within this 45mm collection, key variables that drive value and desirability include case material, dial configuration, and gem-setting level, with full sapphire crystal skeleton references such as the 411.JX.4802.RT and 411.JR.4901.RT commanding strong premiums over standard ceramic or titanium builds. Limited or boutique-exclusive editions like the San Francisco Boutique ceramic orange reference and the Sang Bleu geometric dial collaboration attract collectors seeking pieces with restricted distribution and unique dial architecture. Condition, box and papers, and whether a piece is listed as brand new versus pre-owned are equally important factors when comparing similar references side by side.
Frequently Asked Questions
What makes the Hublot Big Bang Unico 45mm different from smaller Big Bang sizes?
The 45mm case is the flagship expression of the Big Bang Unico line and houses Hublot's in-house Unico flyback chronograph movement, which was designed specifically for this larger case diameter. Compared to the 42mm or 38mm variants, the 45mm offers a more architecturally imposing profile and is the size most commonly chosen for limited editions, gem-set bezels, and exotic case materials like full sapphire crystal or red ceramic.
Are the 45mm Hublot Big Bang watches at Bizak and Co. authentic and what condition can I expect?
Every watch in this collection is authenticated by Bizak and Co. before being listed for sale, and condition details including brand new designation are noted directly in each product listing. Brand new pieces such as the 411.OM.1180.RX King Gold Ceramic Skeleton and the 411.JR.4901.RT Red Sapphire Crystal Skeleton are unworn and come as they left the boutique.
Which 45mm Big Bang Unico reference is considered the most collectible?
Full sapphire crystal and baguette diamond references like the 411.JX.4802.RT Sapphire Baguettes Diamonds and the Rainbow titanium 411.NX.1117.LR.0999 are among the most sought-after due to their limited production and complex finishing. Collaboration pieces such as the Sang Bleu ceramic 415.HX.2027.VR.MXM19 also carry strong collector appeal because of their restricted release and distinctive geometric dial design.
