This watch is about 42mm wide, and will fit an 8 inch diameter (or smaller) wrist. It was my every day watch, but someone recently gave me a Fifty-Five Fathoms tribute watch, and I can only wear one watch at a time, so I am selling this one. The chronograph has a few signs of wear. What I like best (besides the blue watch face) is that it is powered by light. It never needs winding or batteries, and will be sent to you in the Seiko watch box that is shown in the picture.
