Seiko 6159-7010 “Grandfather Tuna” titanium 600m dive watch
This is an entirely original and original to itself Seiko 6159-7010 600m automatic hi-beat diver. It was made in October 1975. The watch hand-winds and automatic winds.
All parts of the watch are original and original to itself.
6159B movement has been serviced by me, including rebuilding the mainspring barrel.
Dial and hands are original - original lume, original patina
Case finish is entirely original. Caseback shows typical wear from use, but no abuse.
Crystal is the original one to this watch. It has some minor marks but the clarity is excellent. Normally I’d replace a crystal with any wear, but this one looks so nice, and it is original to the watch, so I left it.
Crown screws down all the way, smoothly and cleanly
No chips on the ceramic finish
Watch will come on a brand-new Uncle Seiko recreation of the GL831 strap
