Vintage Watch Servicing: What Should Be Done?

[wuyeah]

Hello guys,

I just got a DateJust inherited from grandpa given by my mom today. The watch is worn well and runs. After I unscrew the crown and checked the bracelet, immediately know this DateJust def needs a bath. There is a crack on the plexiglass so I bring it to RSC for quote. After the examination, Rolex watchmaker suggest to replace the movement parts while he still has parts. This piece is with Rolex 1570 movement. So I def would do a full service on it.

Now the cosmetic. I can afford everything RSC have ask for but since this is a vintage piece, I am not sure if I should done everything. Crystal has a crack so will relate to water resistance and moisture, so it is a must but for the rest should I touch it? I am afraid if I touch some cosmetic element will ruin the value of a vintage piece. Sometimes, a vintage watch should keep its look but I am not sure if this is the case. I want the best for this watch in collector perspective. So I would like to ask if following element I should get it done:

1) Hands Polish and re-lume
2) Dial Relume
3) White Gold Bezel Re-done. So it looks white not yellowish. Polish and sharpen fluted bezel edge.
4) Case Poslish

If full service won't damage the vintage watch value, I am willing to refresh all. For some reason, I feel strongly that I should keep the dial lume and hand lume the way it is. As for Case, bezel and bracelet I don't mind to give a fresh new look. What's your opinion about it?

Thanks in advance.
