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
