Great simple calculator here to help determine what a purchase back in any year, at those dollars, is equal to in today's dollars or vice versa.

Back in 2002 I was looking at buying either a gen Explorer 1, gen 16710 or 16610. I stupidly passed on all three. I thought the sub and GMT were too large for me and I read a scathing review on Timezone for the Exp 1 which later turned out to be a complete fraud. What the hell was I thinking? Anyway, the retail price for the Explorer was $2,200 approximately. The sub and GMT were around $3,100 or somewhere in there? I can't completely remember but those are approximates.
Using the calculator above, and then taking a look at what these gens are selling for today on the used market, they would have actually all broken even or would have put me ahead after factoring in the sales tax I would have paid back then. Not to mention that I would have been wearing and enjoying whichever one I had purchased.
Not sure how today's modern ceramic subs would compare, considering the ridiculous price increases Rolex has issued. I think they are shooting themselves in the foot, personally. Today's prices are just way too high.
