Pay to Service Rolexes I Don't Wear?

[BB83]

Hi everyone, could use some advice...

I have two Rolexes that have sentimental value to me but that I do not wear - they just sit in the safe deposit box.

One is a 1984/85 YG Day-Date with diamond bezel/markings. I don't think it's ever been serviced, and I'm pretty sure the diamond bezel is aftermarket, so not sure if official RSC will service it (maybe SF will?). Day mechanism isn't working, and the bracelet has a large ding in one link that would be nice to fix. The second is a 1995/96 TT Datejust with what the AD tells me is a unique rotating gold bezel. It's never been serviced either but runs great. I am the original owner, but didn't know back then how important it was to keep the papers (ugh)

I'd appreciate thoughts on whether it's worth it to service one or both of the pieces seeing as I don't wear them (neither is my style, and love the Daytona too much to wear anything else!). The Day-Date needs the service more due to the non-working Day function, but it has original papers; servicing the Datejust would have the benefit of giving me service papers and that instant authentication. Curious as to what I might be looking at in terms of service cost, and whether it's worth the money if they're going straight back to the safe deposit box after.

Thanks!! (Btw I'm leaning toward servicing them both because I plan to start a larger collection and want to have all pieces in great shape -- but I guess that has to be weighed against using that money to buy more watches!)
