... this is assuming we're talking about stainless steel Rolex Submariners....
apporximates here,
I think Freddy posted that when subs first came out in the fifties they were ~$250
as per this thread ~$400 in 1980
I paid $2,200 for mine in 1992
$ 7,375 in today's Ben Bridge mailer
makes for an interesting chart.
"percent increase" is relative to original price
"percent change" is between subsequent data points...
This one I sent back to Eurotimez for a movement replacement just before they departed the planet. I regret that I didn't just deal with it here and take it to a local watchsmith.
