Bracelet Refurbish & Aftermarket

[maximumk]

Hey everyone, first post!
I just purchased my first Rolex ever, a 1966 Datejust 1601 with a gold pie pan dial and white lettering. I want to refurbish the stretched out jubilee and have a couple questions for all you experts out there:

-Reputable and high quality bracelet refurbishment
-Good quality supplier of aftermarket bracelets so that it can tide me over while I wait for the multiple week turnaround for the bracelet service

I assume that your answers might be helpful for many and my apologies if I've missed a previous thread elsewhere on the forum.

Thanks!
