To polish or not to polish

[Musselman]

My father gave me his original day/date (given to him by his father) and I’ve not worn it much as it had a brick bracelet which is a bit much for daily wear. I’ve recently changed to a leather strap which I much prefer. I’d asked my watch service guy about polishing ans the dial is a bit dull. He advised against it due to devaluation and also losing some of the gold. However, if I’m just going to wear it and never plan to sell it, are there any other considerations I should think about? Any advice would be appreciated. Thanks in advance
