Seiko 5h26-7a19 cross reference help?

[plugugly]

I originally posted this in the general watchmaking forum, without much help showing up, so I thought I'd repost it here to see if the Seiko specific forum was where I should have posted it. Sorry for the duplication, not trying to spam the board, just looking for some help.

I've got an older Seiko 5h26-7a19 (quartz pepsi diver) watch that I'd like to play around with doing some watch work to. It's currently non-running, I assume because of the battery. I bought this watch new when I was in the Navy, and it's seen it's share of abuse. I thought it would be fun to try to spruce it up a little and see if I like working on watches. I'm pretty handy otherwise, but need help with terminology and compatibility, so I can get the right stuff. I've spent hours looking around the internet and these knowledgeable forums, and think I can ask the questions in a way that I can be understood. I ordered a basic set of tools from 10watches.com, which is still en route, and a hand crystal press, so I guess I'm committed .

The biggest problem I'm having is that the watch didn't have a very long run, and finding parts by the case numbers is problematic. Looking at Jules & Borel, I can find many parts I need, but not all. It needs a crystal, a battery, a bezel insert and I'd replace the gaskets for the crystal and caseback when I replaced them. The bezel insert is one area I'm having trouble, they don't seem to list just the insert, but do seem to have the whole bezel ring. Without pictures on the website, it's hard to tell what I'd be ordering.

The other question I have is about the face and hands, and their interchangeability with other Seikos/watches. My lume is about nonexistent, and I have seen many neat faces on the web and wouldn't mind updating the face and hands to something newer, with fresh lume. I was hopping someone could tell me what I need to know/measure to get something that fits my watch. I'm not opposed to re-luming, or sending it off to be re-lumed, but a facelift seems like it would be fun, and having a unique watch appeals to me. I understand the watch isn't worth much, and am just doing it for fun, so I'm trying to keep costs down.

I think I understand my watches numbering, but am ready to be corrected. The 5h26 is the movement, and the 7a19 is the model, correct? So I guess what I'd like know is what (if any) other numbers or watches can I browse parts for, and have the faces/hands interchange? Is it a lost cause trying to find interchangeable parts?

Thanks in advance for any help you folks can offer, I look forward to reading your responses, and my new hobby of watch fidddling.

Seiko did not manufacture bezel inserts by themselves. They only sold the complete bezel. On this model the bezel is a rotating ring and the one you need is 86311246.
There are aftermarket sites like 10watches.com and yobokies that might have an insert that would work.

The same goes for hands and dials. The concerns are dial feet location, diameter, calendar window and hand hole sizes. I doubt that you will find compatible dials from other watches but hands shouldn't be hard to source.

Thanks for that help, I've poked around 10watches and other sites, which led me to my questions about cross referencing. They obviously don't list parts for the 5h26, so I was really hoping someone would say "Any quartz Seiko hands will work" or "any 28.5mm Seiko dial will work". I'm finding out this either isn't the case, or no one really knows. I was really hoping some one would pop up and say parts from the SKX009 or SKX007 will work in/on my case, then I'd have a ton of options.

I have an Orange and Black Monster, so I may try to see if I can interchange the movement into the 5h26 case. Then I might be able to just buy a 7s26 movement from someone like 10watches, and go crazy. I think the problem will be case depth, and don't know about crowns, either. I know that the bezel mechanism is different, as I've had both off and the spring is different. At the time, I didn't think to get the micrometer out and see if the sizes were close.

If nothing else I'll practice taking dials and hands off on the 5h26, so if I want to change them myself on my Monsters I have some experience.

Any luck with reburbing your watch and finding parts?
I have one as well that needs a complete overhaul. it quit running a few years ago and i put aside to deal with it later. i pulled it out the other day and the hands are corroded. i am guessing i need a new movement, face and hands. Not real worried about crystal and bezel as they get banged up with normal wear.
thanks
