The see-through case back reveals the movement in motion, reinforcing the unique appeal of a mechanical watch. The raised indexes, sharp case and bezel design, and sapphire crystal project premium quality all the way. Water resistance up to 100 meters leaves you free to focus on more exciting things. Designed to thrill the most passionate car enthusiast.
