[TECH] SEIKO "KING SEIKO" 4502-7001 "45KS" Teardown PART 1 - The Case

[@christopherwilliams4552]

Thanks for this! The 45KS is one of the watches I hope to have in the next 12-months. More info is always better.

[@hal0eight]

They are pretty cool and mostly in good condition. They are like a racehorse though, probably not a good daily wearer as they do wear faster than a lower beat watch.

[@christopherwilliams4552]

I like the racehorse analogy :-). When I get one, I will keep it out of winders, which I wouldn't use anyway. I appreciate the reply and the role you play in the vintage seiko community.

[@firas5649]

Nice watch, I look forward to part 2.

[@hal0eight]

Thanks, will be out very soon.

In the back plate is real gold... Hope to reply thank and more power your vlog

[@WatchGeek]

Could you measure the diameter of the caseback and the diameter of the thread of the caseback as I am trying to source or make a see thru caseback

[@hal0eight]

Geday OD of the thread is 30.9. It might be worth seeing if some 6138 CB's will fit and carving one of those up. Or maybe a 7017, They have the same thread I think. I'd have to check.

Hi what is that circle removed at 2:42? Is that the gasket?

[@hal0eight]

No, casing spring.

[@MDVH92]

Hey Adrian, do you have any idea on the dimensions of a suitable crown gasket and mainspring for these 45XX movements? Thank you in advanced! I'm looking forward to the release of the VTA KS buckles.

[@hal0eight]

Crown gaskets are a problem. I may have a solution later this year. They are a swiss crown so you need to press it apart. mainsprings are another huge problem. Nobody makes a suitable mainspring. I'm working on that this year as well and will hopefully come up with an answer.

[@MDVH92]

@@hal0eight sounds like a 45KS restoration starter pack, gaskets, buckles, and mainsprings. I'll keep my eyes open. Thanks for the reply!

[@jeanducheamps7697]

Why not show the removal of back, stem and front?

[@hal0eight]

It's a bit boring? Plus handling stuff on camera is difficult and I don't like dropping movement + dial attached.

[@danielfernandez5721]

How much is the usual full overhaul for these? I really want to get one but am concerend about service and parts availability.

[@hal0eight]

Best to email me on that one. Usually movement parts are OK unless it's been messed around with before. Any cosmetic parts are basically impossible to find.
