I purchased this a while ago. I haven't confirmed its operation, so I don't know if it will work after replacing the battery. The watchmaker removed two or three links from the band because my wrist was small. There are minor scratches from use. For those who understand that this is a used item. Thank you. Band material: SS (Stainless Steel) Actual size: Face: Approximately 2.1 cm x 2.1 cm Case: Approximately 3 cm x 2.6 cm (excluding the crown) Band width: Approximately 1.2 cm Wrist circumference: Approximately 14 cm
