PRICING:
This is a very collectible and uncommonly seen chronograph wristwatch with very consistent pricing. I believe the fair market value of your watch in today’s demanding market place would range from $2300-$2700, with retail prices at least twice that amount. Congratulation on owning this fine example.
My best,
David
