What watch band for '60s Omega Seamaster 600?

[Bassman]

So...my uncle that claimed to find another wristwatch on the subway every couple of months died and I got a cigar box with a few watches and bands inside.
These sat in a drawer for years until yesterday when I figured I'd take them into a jeweler and see if any were worth even winding up.
The scoundrel...I mean jeweler (name available upon request) informed me that 3 were garbage, but he'd give me $20.00 for the Omega which he could use for parts.
I declined his offer, figuring I'd wind that one up and if it kept time, I'd start wearing it. I was totaly clueless about what this might be.
Then I poked around on the good ol' internet and it appears that this is a vintage Omega Seamaster 600 in stainless steel, with no scratches and it's keeping time just fine.
Anyone have an idea what kind/color band may have been on this originally?
If anyone is knowledgeable about this timepiece, I'd love to hear more about it.

$20 for parts? At least you know where not to go in future. Seamasters are a nice watch and have quite a following.

I think the color of the strap would depend on the color of the dial and markers. For correctness (if that is a concern) you should consider an Omega buckle to match the watch case

Seamasters also came with stainless bracelets as well.

Given the veracity of your watch guy, some pics of the other units would be nice. Perhaps they are not junk at all.....
