This is a Citizen OXY Eco-Drive diver's watch for men. The new secondary battery was replaced last month, October, and it is currently running accurately. The original bracelet has some minor scratches from daily use, but the crystal is scratch-free and the watch is in overall good condition. The case diameter is Φ 38 mm, the thickness is 11mm, and the wrist size is approximately 17 cm. There is no play in the crown, and the hands and calendar can be adjusted correctly using the crown. The unidirectional rotating bezel moves smoothly. There are no extra links, and this is a watch-only sale.
