Double Coupling System and Column Wheel: A Symphony of Precision
The 421.HX.1170.RX boasts a sophisticated double coupling system and a column wheel, both visible from the dial side through the "open heart" design. These components are crucial to the movement's functionality and represent a significant step forward in watchmaking technology. The column wheel, a hallmark of high-end watchmaking, controls the chronograph's starting, stopping, and resetting functions with exceptional precision and smoothness. Its presence in the 421.HX.1170.RX underscores the movement's refined nature and its commitment to accurate timekeeping.
The double coupling system, also visible on the dial side, further contributes to the movement's precision and efficiency. This system ensures that the chronograph functions flawlessly, preventing any interference or drag between the chronograph mechanism and the main timekeeping function. This contributes to the overall accuracy and longevity of the movement. The strategic placement of these crucial components on the dial side is not just about functionality; it's a bold design statement, a testament to Hublot's confidence in showcasing the technical heart of its timepieces. It's an invitation to explore and understand the mechanics behind the artistry.
