What to check when buying a used Daytona?

[unstoppable]

Hi All

I’m going to a well known jewellers tomorrow to view a used Rolex Daytona that I’ve enquired about.

It’s white dial 2004 model, with steel bezel and obviously used though I’m told the condition is very good.

I haven’t really bought a used Rolex before as my previous Rolexes were new from ADs.

What are the things I should look for and ask about? Any advice and pointers will be appreciated.

Also what should come with the “full set” for this particular watch?

Any advice appreciated.

Many thanks.
