Thank you for viewing. This is a rare Citizen C-mark buckle. Most commonly available are aluminum, but this one is stainless steel. Considering the domestic sales share at the time, this model is very rare, and it was originally attached as a genuine part to the belts (when new) of high-end Citizen Chronometers and other luxury watches. The condition is quite good, with no major scratches. The attachment width is 15mm. Thank you for your consideration. #Citizen #ManualWinding #Genuine Color: Silver系 (Silver-toned) Accessories: None
