Advice on dealing with scratches

[Alizawi]

I have a 5 year old RO 15400 which has some noticeable scratches (from some angles heart breaking, to me at least). Forget wrist awareness, as I am generally a clumsy person. I am also usually a "one watch at a time" person, so This is what I wear on a daily basis, for all occasions.

Now I have heard negative things about sending the watch for polishing, even more so if I ever decide to sell it. What is the general guideline here?

I'll put up some photos shortly showing the scratches.

Thanks..
