Refer to the above table that states the Rolex AD MSRP price of Daytona Ref 16520
I ploted a chart to tell how does it run over these years... as below
What is the best investment for the past 35 years in HK!??
A house like Mei Fu Shun Chuen, that was about $30,000 in 1968 and about $250,000 in 1980 and now is $9,880,000 per unit.
1980 to 20156 appreciatioon factor is about 40 times.
Whereas if you bought that Rolex Daytona Steel Ref15620 in 1980, your cost was HK$3,725.
If you don't use it, keep all Full Set until now, Minimum you can sell as good as HK$98,000 (selling price of Such new Ref 116520 Daytona in Rolex AD) your minimum profit gain is $94,275.
Appreciation factor is 98000/3725=26.3 times.
But who know if you put it in Auction, since it is still mint condition, you may go for an Auction of $200,000 (my rough estimation), that is a higher gain factor (53) than Mei Foo Sun Chuen !!
