Bokey TimeLS Factory presents the Hublot Big Bang 431.OM.1338.RX 20th Anniversary Edition under the LS1 premium release, celebrating the iconic legacy of the Big Bang collection.
The watch features a newly developed 43mm case created from original new molds. Compared to market versions that use older 44mm cases based on the 301.SB.131.RX platform with more protruding chronograph pushers, this edition adopts a fully redesigned ergonomic structure with refined detailing. The case includes larger polished bevels and precise finishing, with dimensions of 43mm by approximately 15mm, faithfully restoring original proportions.
The date display has been structurally upgraded through movement modification, positioning the date window accurately at the edge of the dial in line with the original specification. Compared to standard market versions with misaligned date windows, this configuration offers improved authenticity and visual balance.
The three o’clock chronograph subdial has also been redesigned to match the original large-scale circular format. Unlike standard versions where the subdial is reduced due to date window interference, this edition restores correct proportions and layout consistency.
It is powered by the HUB1280 automatic chronograph movement, delivering precise timing performance and a 72-hour power reserve, representing a high level of mechanical stability and engineering refinement.
The watch is equipped with a quick-release fluororubber strap system, allowing effortless strap changes while maintaining comfort and modern sporty aesthetics. The strap is made from imported fluororubber material, offering a softer feel and improved wearing comfort.
The sapphire crystal provides high transparency and strong anti-glare performance, ensuring clarity and durability under daily conditions.
Commemorating the 20th anniversary of Hublot’s Big Bang series, this limited edition integrates signature design elements with advanced watchmaking craftsmanship, embodying the spirit of innovation and breakthrough that defines the brand.
