FS: Seiko TUNA CAN 7549-7010 Vintage 1978

Dear ChronoTrader readers,

“There’s nothing else like it at all.....”

Up for sale today is my Seiko 7549-7010 also call "TUNA CAN" dated May 1978.
My TUNA is all original and this rare and nearly mint watch is an essential part for any serious Seiko Diver Collection.
It has historical significance and it’s a part of the Seiko dive watch lineage.

Except the outstanding shape of this piece I wanted it to be completely operational for diving and my watchmaker has changed all seals by an original Seiko kit seals and tested the watch in situation: waterproofing warranty and pleasure tenfold for the future user who can use this wonder diving vintage !!
Water resistance: 300m/990ft/30atm.
On this occasion watch has also been serviced and all functions (time keeping and day/date) are in perfect working order.
