Hublot presents the Big Bang 411.JX.4802.RT “Full Transparent Watch,” recognized as a standout high-end replica interpretation of the Big Bang series.
This model faithfully reproduces the original openworked dial architecture, capturing its dynamic skeleton layout and fluid mechanical aesthetics. The design emphasizes a fully transparent visual effect, showcasing the depth and complexity of the movement structure.
The case uses high-grade acrylic organic glass with exceptional transparency and durability, offering strong hardness, corrosion resistance, and wear resistance. It is paired with a high-definition scratch-resistant sapphire crystal, ensuring long-term clarity and protection.
The watch measures 45mm in diameter and is powered by an enhanced 7750-based chronograph movement modified to replicate the HUB1242 architecture. This ensures full functional consistency with the original chronograph layout and performance behavior.
The production process emphasizes precision at every stage, carefully balancing transparency, structural authenticity, and mechanical realism to achieve a refined visual presentation of the movement.
An additional natural rubber strap in a different color is included as a bonus, providing an alternative wearing option to the original configuration.
This model is positioned as a fully transparent skeleton chronograph concept piece, combining bold visual design with mechanical depth and modern sports watch aesthetics.
