Purchased as a used item, the parts were cleaned, partially polished, and the battery was replaced. There are some minor scratches on the crystal and case, but I believe they are within the range that doesn't affect use. I haven't tested the water resistance, and I cannot guarantee it due to amateur maintenance. Case diameter: approximately 30mm Thickness: approximately 11mm It's a lug-sport style with integrated lugs, which I think makes it versatile. The band is free-size because you can adjust it by sliding the adjuster on the 6 o'clock side. I might change the selling format, so please "like" it if you're interested. #Watch #SEIKO #Seiko #Lugsport
