Rolex Polishing

[tudk]

I am new to the forum.
I recently sent my nine year old gmt into Rolex via an AD for service.
I wear this watch everyday as I believe a watch should be worn not
hidden away .It is scratched as you would expect with everyday use.
I would be satisfied with just a mechanical service however they offer
a polish with the service.
Yesterday we are at an AD in Melbourne Australia and the salesperson
advised that polishing if done by Rolex would not harm the watch.
I read on this forum that polishing can round the edges on the lugs
and distort the shape of the crown.
Would appreciate people’s thoughts on polishing done by Rolex.
