1971 datejust needing restored, help

[skip82]

Hi all, im new to the site and just purchased a 1971 Rolex 1601 datejust, it has gold bezel and trim on the band, it runs perfect but has been worn by previous owner for 49 years, where should I send it for restoration and what can i expect for a cost, Im no watch expert but would think it will need new crystal, face plate and such and polished up.

Thanks: Skip
