This is a Citizen xC (Cross-Sea) EC1010-57F. I purchased it at Bic Camera in 2014. I have only used it once, so I think it's in good condition. *This is a personal opinion. It is a radio-controlled watch, so please use it in a place where sunlight reaches. If used in a place with low sunlight, the hands may move slowly. Please forgive any age-related scratches or marks as this is a used item. Please refrain from purchasing if you are overly concerned about such things. Returns and claims are not accepted after purchase. Please examine the product carefully and consider purchasing only if you are satisfied.
