....... I really don't know how much you know about your patek 3700,
but one of the most attractive aspect of a nautilus is the octagon shape of the bezel,
those lines ONCE polished most certainly will be smoothen out, I guarantee that.
base on the pictures you provide, it seems the bezel hasn't been touch much ....
I don't know if and when you bought this watch, was condition part of the consideration ?
if you send this watch for a movement overhaul I wouldn't have said much,
even the bracelet may need a bit of buffing up .... but the contrast will be quite noticeable.
best you do the movement, ask for a bracelet clasp ....and leave the rest.
but if you are a spick and span kind of a guy, then I say no more.
