The only precious metal watch in your line up which ‘may’ prove a reasonable investment is the Daytona, but you need to like it, as you’ll be wearing it.
The mad increases in values has not affected precious metal watches, excluding mainly Patek. Most can be bought with a discount.
Investment - get on lists to buy steel sports Rolex. Otherwise, negotiate hard and minimise the loss you will make. A watch is an object and will depreciate.
For clarity, I own a white gold Sky-Dweller. UK Retail £29,100, I paid £23,000 2015. Then discontinued and a steel version launched. Trade would pay me £17,000, while steels are selling over RRP not much less.
