About this watch

The Hublot Big Bang Unico 45 Red Sapphire is a stunning luxury timepiece that embodies the brand's commitment to innovation, style, and craftsmanship. This limited-edition watch features a bold red hue, a skeletonized design, and a transparent sapphire case showcasing its intricate movement. The combination of titanium and sapphire offers a lightweight yet robust feel, while the sapphire crystal adds a layer of scratch resistance. At the heart of this masterpiece is the Hublot Caliber HUB1242, an automatic movement developed and manufactured in-house that guarantees reliability and precision. With 38 jewels and a power reserve of 72 hours, this flyback chronograph boasts a column wheel and double clutch, visible on the dial side. The watch's analog display is complemented by stick hands and mixed indexes, ensuring easy yet visually satisfying timekeeping. Measuring 45mm in diameter, this bold statement on the wrist makes a lasting impression. With a water resistance of up to 50 meters, it's perfect for everyday adventures, but not designed for diving or high-pressure water sports. Its limited production run of just 250 units adds to its allure and value, making it a true collector's item.
