Ls .Factory presents Hublot Big Bang 431.Om.1338.Rx 20th Anniversary Edition. 1. Original 43mm case (market version 44mm), using the case of the old 301.Sb.131.Rx model. The two chronograph pushers are prominent. It's not a direct copy. It features a completely redesigned, more ergonomic case with more refined details. It has larger polished chamfers. The size is 43mm~15mm. The 43mm wide case has been carefully refined to match the original size. 2. Upgraded date window. Through movement modification, the date window has been pushed to the edge of the dial, unlike the standard market version. 3. The 3 o'clock minute counter is a large round dial, unlike the standard market version where the 3 o'clock minute counter is limited to a small round dial due to the date window. 4. Powered by the Hub1280 automatic mechanical movement, this watch precisely drives the chronograph function with a 72-hour power reserve, showcasing the pinnacle of mechanical art through exceptional performance. The one-click quick-release fluoroelastomer strap allows for easy switching between different wearing styles, balancing comfort and trendiness. The strap is made of imported fluoroelastomer for a more comfortable and better feel. The sapphire crystal is clear and anti-reflective, ensuring clear visibility for everyday wear. A tribute to classic heritage and innovation: To celebrate Hublot's 20th anniversary, the Big Bang series presents a limited-edition commemorative model, blending iconic design with cutting-edge watchmaking craftsmanship to pay homage to the pioneering spirit of the era.
