I think the question you need to ask yourself is what do you need the watch for? If it is merely to tell the time, then a £10 Casio keeps better time than a 10K Rolex. Trust me, I know.
However, if you’re wearing it as a piece of jewellery, lifestyle statement, or a status symbol, then you may want to choose something else? Watches, clothing, personal grooming are all personal choices.
