Both tell the time & the Argos one probably is probably more accurate.If it's rubbish that people buy for one upmanship what tell o wise one is the function of a Rolex over an argos watch?
However I bought my Rolex Submariner because I wanted one as a present to myself for my 50th birthday. It is also an investment which has perfomed better than most of my other investements over the same period. It will probably pass on to my Grandson to do as he wishes with.
I recently bought an Omega seamaster because I wanted one of those as well.
