Welcome to the forum George.

Steve has pretty much nailed your watch for you, it's a 73443 T (if it has a black Tachymeter ring around the dial) or 73443 S (if there is no Tachy ring) from circa 1970/1 onwards:

By the time we get to the 1972 catalogues, there are no Camaros, so these particular watches are quite easy to date as having been manufactured in either 1970 or 71. And the second number you provide is the serial number - 232xxx suggests a date late in 1971 rather than anything earlier.

Interestingly, we have only recently been discussing one of the other watches in the first catalogue picture:

But this is another excuse for me to post my Carrera equivalent to your Camaro again:

I reckon Steve is right on the values too - the low value would either be a very good bargain or a project watch with issues, so for an insurance value you should be taking the upper limit and maybe adding some more to it too, as is usual with replacement values for insurance.

As for wearing it, this is a pretty robust movement and can certainly stand up to daily wear - if it has been a while since the watch was serviced, it's a good idea to get this done, at least to ensure that the oil reservoirs in the movement haven't dried out. As to whether the value would preclude you from wearing it, that's for you to decide, but I'm definitely in the "vintage watches are for wearing" camp myself!
