This rare Seiko 5 Sports 6119-6400 "UFO" or "Saucer" dates to the early 1970's and as the name would suggest, features a unique "UFO" style stainless steel case with recessed crown located at the 4 o'clock position. This crown on the 6119-6400 actually operates the inner rotating bezel, hour/minute hands, and the day/date window - the watch can not be manually wound. The watch benefits from a recent service and is wearing a Seiko stainless steel bracelet with folding clasp.
