Motorsport cues and a modern case design push this Roger Dubuis Excalibur Spider Huracan ST EVO2 Carbon Black Dial LIMITED toward the sharper edge of the Excalibur line. The 45mm case in alternative material, black dial, and rubber strap give it a dark, technical look. Its automatic movement keeps the watch straightforward in daily wear. At 14.5mm thick, it has broad, architectural presence on the wrist.
