Please pardon my ignorance but isn't the 7c46 just another quartz movement? Please educate me!
Great post Jim, I enjoyed the read thoroughly. Love the tuna's, nice to know why I love them so much and more so now.
Geez Jimmy - where do you get this stuff? You're a legend mate!
Just look at how well these 7C46 movements will hold time within specifications ,even after decades of usage...that's the proof it aint just any quartz..
some of my old seiko ordinary movement quartz have long kaput...but the tunas(7C46) remains solid and sharp on time.
houses such a quality specialized movement such as the 7C46!
I agree that it makes owning the Tuna that much more interesting and special to it's owner, considering both are only found with-in each other, in what I and many others like you feel is the absolute highest quality Professional working tool Diver available IMHO.
Thanks Dave & Dive watches Rule! ;-)
any thoughts on the 7548, the sibling of the 7c46?
I'm thinking on picking one up for restoration.
