Hi all,

I'm sorry if this is the wrong forum (and not a vintage) but I need advice. So my wife wants a gold rolex (to wear on occasions) and I'm after something sentimental.

I have found a DD36mm from my birth year (late 80s) for a reasonable price, on sale by a reputable Antique shop in London.

It is the reference number 18038 and the pictures show a fantastic watch with hardly any signs of stratching.

There is an original box but no original papers.

I had a few questions:

1) Is there anything I should be worried about?
2) Is there a way of verifying the age without the original papers?
3) I would never sell this watch but rather pass it on to kids/future grandkids, but is this likely to be a watch that would always hold value?

Thank you for your time
