NOS Rolex bracelets

[Juantxo]

Hello. This is my first post on this forum. I'm grateful to be able to participate with you discussing Rolex watches.

So far I own a dozen Rolex, all steel except one, all bought new except one.

Presently I'd like to switch the bracelet on my 16800 Submariner for a new one (or a new old stock one). This is the only Rolex I own which I didn't buy new form an authorized dealer.

Also, I'd like to switch the Oyster bracelet on my steel beveled bezel Datejust. I'd like a new (or new old stock) Jubilee bracelet for it.

Of course, I'll appreciate greatly your suggestions as to where I could find the bracelets I'm after. Thank you so much.
