Buyer's Comments

This is a Citizen Challenge Diver automatic watch. It has a black dial and Mercedes hands, giving it a strong presence. There is age-related deterioration on the crystal and hands, but overall it is clean. The case has minor scratches, but no major damage. Operation is smooth. An aftermarket strap has been attached.
