The bezel actually turns quite nicely, so not sure why it won't align correctly.
Pretty sure the crystal certainly isn't 'new' - what gives you that impression?

 

I've had a new crystal fitted to my early Tudor sub and it interfered with the bezel turning. The crystal was reduced very slightly in diameter to clear the bezel, I thought that maybe.......

 

ah, i see. no, it turns just fine. it just doesn't line up.

 

If the bezel turns okay but doesn’t line up correctly it’s likely that the bezel insert has moved. To fix it you would need to remove the insert and put it back correctly aligned, however I don’t recommend you try it as the insert is very fragile and you’ll likely break it.

 

I agree. even IF the bezel could line up exactly on point there is still plenty of wabi and random imperfections to trigger another OCD flare-up. leave the freakin thing alone and focus on finding a decent bracelet. I bet that thing would pop on one of uncle Seiko's jubilees!

 

Actually, it's more likely to have come that way from the factory. Even the modern replacements cases had a time a while back where a bunch of bezels didn't line up properly. Watchco sold a pile that were misaligned - I know, I have one of them.

 

Point fully taken - and besides, i'm growing to like its misalignment, now i could believe it left the factory like that. it's endearing.
Last question: what is an appropriate-era 16mm buckle for the leather strap? (for some reason, i prefer a retired vintage diver on a leather strap rather than a bracelet)
...and a good supplier of an aftermarket example? I have the attached at the moment and it's just not quite right.

 

That buckle is horrendous and Omega is remaking the ones with the raised logo of that style but not looking smooshed.

When I get a chance I'll take a pic of the buckle I like for that era.

Thanks Tom, would like to see that.
Something like this?

 

This is what I have on my Seamaster 300's Tropic when I'm in the mood for it.

Not the best pic but it's a stamped buckle with a raised symbol.
