CITIZEN COLLECTION MECHANICAL OPEN HEART WATCH

Citizen's 2026 Collection Mechanical Open Heart lineup combines an exposed balance wheel with a modern 41 mm steel case and a display caseback.

The open-heart aperture at 7 o'clock reveals the movement in motion. Mirror-polished bezel cuts, beveled bracelet links, and sharply finished indices create contrast across the silver, black, blue, and two-tone variants.

Caliber 8229 provides automatic and manual winding, stop-seconds setting, and approximately 42 hours of running time in a practical Made in Japan package.
