Just an update:
Checked some prices on classic 60s Era Chronographs and almost all have doubled or tripled since this thread started.
Seems like every watch company has re-issued or limited edition of iconic 60s Professional, Pilot, Diving, Space and Racing Chronographs.
Everything from Tudor Chronograph Monte Carlo, Tudor Blue Sub, Omega PloProf Diver, Omega Seamaster 1000M, to cult classics like DOXA, Aquastar, Certina, Glycine Airman, Aquadive and Roamer Stingray.
This is a massive run-up; watched this market daily from 2000-2008; '10-'14 is off charts.
Ex: Below were all in $150-1,000 range in last decade on ebay.
Heuer Monaco NOS $15,000
Tudor Monte Carlo $15,000
Heuer Autavia GMT $8,00
Heuer Autavia Slide-Rule Calculator $4,000
Glycine Airman SST 24h Chrono $5,000
Omega PloProf $5,000
Omega Sea Master Chrono 120M/400f $6,000
Tudor Chrono (Pre-Tiger) $5,000
Zenith El Primero 'Big Blue' $5,000
Zenith El Primero Pilot $5,000
Omega Flightmaster $4,000
Aquastar Benthos 1000M $4,000
Aquastar Benthos 500M $3,000
Hamilton Pan-Europ 707 Chrono $2,500
Sport Lemania 5100 / Valjoux 72, 77, 7500 Chronographs (Longines, Bucherer, Nivada, Zodiac, Sinn, Hamilton) $min $1,500+
Seiko Auto Chronographs $500-$1,500
My collection, which were $500-$1000/ea. watches went from $30,000 to $90,000 (stored in bank vault!).
Probably should have waited in '08 to sell off 25 watches, for Vette, could be in ZR1 or C7-Z06 instead of C6!
Some of these will become Daytona money...esp. Tudors and Omega Divers.
