Seiko
For auction is a 1975 Seiko 6159-7001 Grandfather Tuna 600M 51mm excellent original condition. The Good: 1. An overall excellent example with minimal wear on the body. This watch has been in my collection for some years and I wore it less than 5 times. 2. Patina is creamy and evenly matched. 3. Acrylic bezel is in great shape. 4. Working wonderfully, +0 seconds per day and +273 amplitude. The Bad: 1. I don't know if this qualifies as bad but it is on an Uncle Seiko strap. 2. Watch only.
