Discovering My Grail Seiko: First-Ever Service(?) on a Single-Owner Kakume

In this video, I have the privilege of working on a Seiko 6138-0030 Kakume from June 1975, belonging to an acquaintance of mine. This incredible single-owner watch might be receiving its first-ever service since it left the factory nearly 50 years ago! As I carefully open it up and assess its original condition, I can't help but admire this untouched vintage beauty. After having this watch on my bench, I’ve found a new grail piece to add to my own collection.
