A bold 1970s-style Citizen Automatic with a black cushion case and matching black dial. The silver chapter ring, applied indices and framed day–date window give it a clean, graphic look, while the 21-jewel automatic movement keeps it firmly rooted in classic Japanese watchmaking. A great everyday vintage piece with plenty of character and honest wear.
