Hello here is a Seiko 5 6319-8070 Sports Watch. This watch was a resto mod I did a few years ago. I wore this watch quite a bit the first year I built it. I needed a watch to have the correct time to the second every day to compare with watches I was servicing. So I built this one. It has a Y513 quartz movement. The Y513 is based on the Seiko 75xx series and the 75xx series is based 6xxx series Seiko automatic movement from the main plate upward. They share the same parts. Dials, cases, and crowns interchange.  These movements keep excellent time and the second hand hits every marker without any float. The watch has a Sekosis dial and hands. New crown and caseback seal. The watch is in very good condition. Case and band has some minor scratches. I put a new crystal in it. It has some very small scratches from use. The watch is on a Stelux bracelet and it will fit up to an 8 inch wrist. Watch is 40mm in diameter and has 19mm lugs. It is a great watch to grab and go with a vintage look.
