At the grand old age of 77 I disagree with you about pensions. I don't think that any watch that you buy will provide you with the means of living a comfortable life when you retire. If you are set on buying a watch which will appreciate over time I recommend Patek Philippe. I bought a Nautilus ss with blue dial set with diamond markers 15 years ago. I wear it regularly and it has worn well. A recent valuation for insurance has shown it has appreciated nicely. However, it would never keep me in a reasonable style of living. Buy a watch to enjoy on your wrist and look at the alternative ways of building a portfolio to give you a comfortable life when you are old.
