Perspective on future resale price & choices in life

[watchf]

I need some perspective on some 2 questions from the good folks here.

1) How much would you estimate according to past trends of the resale value in terms of estimated dollars or % of its current price (please indicate if its % of rrp or grey market price) of the below watches in 2, 5 and 10 years time on the used market,

• TT DJ II
• Milgauss GV
• Explorer 39mm
• Sub-C LN

On past trend does the value increases in a linear pattern over time, for example if resale value increases by X in 5 years, it would be about X x 2 in 10 years? In general would the resale value be more or less than its current BNIB price?

2) If you were to choose between two luxury items which you do not need in an objective way, item 1 being a new car & item 2 would be Rollie watches, which one would be a good investment or rather the one you could most justify the spend on if the price on both are almost the same (a new car vs a couple of Rollies)? Lets put the price at say $25k, so either $25k for a car or a number of watches...OR...would you rather have the cash sitting in the bank earning interest?
