The older speedmaster uses column wheel chronos which are more superior than the never cam actuated ones therefore, being part of the reason to be more sought after, and yes i will pay . Most of the prices are derived from demand and supply. The lesser the supply, the more expensive it is. " Rare" , its a very sensitive term in watch industry ... lol.
Some collectors told me new rolexs has not much soul and anyone can buy it from the shop. Vintages are more rare and harder to find, so when coffee time with their friends , they can brag more and will be different from the rest of the pack.
