Bokey TimeThe Hublot Big Bang 431.OM.1338.RX 20th Anniversary Edition is a commemorative timepiece celebrating two decades of the Big Bang series, combining iconic design language with advanced horological engineering.
The watch features a newly developed 43mm case, engineered from original new molds. Compared to market versions that reuse older 44mm cases derived from the 301.SB.131.RX platform with more protruding chronograph pushers, this edition adopts a redesigned ergonomic structure that offers improved wrist comfort and refined detailing. The case includes larger polished bevels and precise finishing, with dimensions of 43mm by approximately 15mm, faithfully matching original proportions.
It is powered by the HUB1280 automatic chronograph movement, delivering precise timing functionality and a robust 72-hour power reserve. This movement represents a high-performance mechanical solution that highlights the pinnacle of modern watch engineering.
The watch is equipped with a quick-release fluororubber strap system, allowing effortless strap changes and flexible styling. The strap is made from imported fluororubber material, offering enhanced comfort, durability, and a refined tactile experience.
The sapphire crystal provides high transparency and strong scratch resistance, with anti-reflective properties that ensure clear visibility under daily use conditions.
As a commemorative edition marking Hublot’s 20-year journey, the Big Bang Anniversary model integrates signature design elements with advanced watchmaking craftsmanship, embodying the brand’s spirit of innovation and breakthrough.
