The Hermès Clipper CP1.910 was an automatic chronograph released in the 2000s, but has since been discontinued. The watch is known for its "porthole" bezel design, inspired by 19th-century sailing ships, and a solid Valjoux 7750-based movement. Key features • Design: The Clipper features a distinctive round case with a porthole-inspired bezel and a three-register chronograph layout. Reviewers have praised its sport-chic appearance. • Movement: The CP1.910 model is powered by a Swiss automatic movement based on the reliable Valjoux 7750. Some variations, like one identified on Collector Square, have a skeletonized caseback that displays the movement. • Case size: The watch was released in a large, modern size for its time. It measures approximately 44mm in diameter and is 16mm thick, making it a substantial watch on the wrist. Other automatic Clipper chronographs may be smaller, so it's important to verify the exact specs for any pre-owned model.
