I don't see your watch in Rich's Price Guide, but would agree that the values should be about the same, as between the first execution and the second execution 2447 Tachymeter.

Perhaps some people prefer the red accents on the first execution and earlier executions often sell at a premium, but the second execution does seem more scarce. Because of this scarcity, it's difficult to state a "fair market value" with any certainty.

Great looking watch, whatever the value may be!! Congratulations!!
