Hublot Big Bang Rainbow Diamond 44mm Clone Watch
The Hublot Big Bang Rainbow Diamond 44mm Clone is a breathtaking expression of modern horology fused with high jewelry aesthetics. As part of Hublot’s iconic Big Bang series, this timepiece elevates the brand’s bold personality with a bezel fully set in rainbow-hued gemstones and fine diamonds. It is the ultimate statement piece for those who seek a powerful fusion of vibrant luxury, mechanical sophistication, and flawless finishing.
Exquisite Rainbow Diamond Bezel
The watch’s standout feature is its bezel—expertly adorned with multi-colored gemstones interspersed with dazzling white diamonds. The arrangement of sapphires, rubies, emeralds, amethysts, and citrines creates a seamless color gradient across the bezel, capturing the brilliance of a true rainbow. Each stone is individually selected for uniformity in size and hue, then precisely set by skilled craftsmen to ensure balance and brilliance from every angle.
The addition of round-cut diamonds enhances the shimmer of the bezel, elevating the already colorful aesthetic into a luxurious visual spectacle. This fusion of rainbow gems and diamonds is rarely seen in high-end sports watches, making this model a standout piece even within the elite world of clone timepieces.
Skeleton Dial with Mechanical Depth
Beneath the striking bezel lies a fully skeletonized dial that reveals the complexity of the Swiss automatic chronograph movement. The layered structure of the movement, visible through the open dial, offers a captivating view of its inner mechanics—including the date disc, visible bridges, and gear train. Luminous hands and hour markers allow for legibility without obstructing the view into the movement.
The sub-dials are positioned at 3 and 9 o’clock, with a floating date display integrated into the open calendar ring. Everything about the dial reinforces the technical identity of the watch, delivering more than just aesthetics—it presents the internal workings as part of the watch’s design language.
Swiss UNICO 1280 Clone Movement
At the heart of this timepiece lies a highly accurate clone of the Hublot UNICO HUB1280 movement. This is not a generic copy—it has been carefully reconstructed to replicate the layout, function, and flyback capability of the original. Key highlights include:
- 60-minute chronograph timer (not just 30, unlike basic 7750 clones)
- 3-digit hollow calendar ring for modern date display
- Column-wheel driven chronograph with smooth pusher actuation
- Horizontal clutch design, closely matching the original architecture
- Daily variance within ±7 seconds and power reserve of up to 72 hours
This movement doesn’t just look like the original—it performs with a high degree of reliability and responsiveness. Every pusher feels authentic, and the chronograph resets cleanly with a satisfying mechanical feel. For those who appreciate technical fidelity in a replica, this model delivers.
Premium Case Construction
The 44mm case is forged from stainless steel with a PVD-treated surface for scratch resistance, then polished and brushed to match Hublot’s original alternating finish. The bezel is reinforced with titanium and ceramic elements beneath the gem setting to ensure durability without compromising beauty. Sapphire crystal protects both the front and back of the watch, offering clear visibility and enhanced resistance to wear.
Other case specs include:
- Case diameter: 44mm
- Thickness: 14.5mm
- Water resistance: 30 meters (daily splash-proof)
- Sapphire crystal mirror with anti-reflective coating
- Transparent caseback showcasing the rotor and gear train
Comfortable Strap & Secure Clasp
To complement the exuberant color of the bezel, this clone features a textured black rubber strap with vibrant accent stitching. The strap is not only soft and sweat-resistant but also fitted with Hublot’s patented quick-release system, allowing users to change straps without tools. The deployment clasp is made from ceramic and stainless steel, engraved with the Hublot logo and polished for a premium feel.
Water Resistance & Care
This model is rated for 3 ATM (30 meters) of water resistance, suitable for daily wear but not recommended for full immersion. Usage tips include:
- Ensure the crown is fully pressed or screwed down before exposure to water
- Avoid wearing the watch in saunas, hot baths, or saltwater without rinsing
- Wipe gemstones gently with a microfiber cloth to maintain brilliance
- Service the movement every 18-24 months to maintain peak accuracy
