Even if it had titanium or platinum workings...actual value is not more than $1000 maybe $2000.
the "workings" are called a movement and that movement is worth at least $1000 on its own. microengineering, especially with diamonds, is neither simple nor cheap.
might be a decent investment too, assuming its ltd edn - my first Tag was an original F1 (yellow/black ploycarbonate), the cheapest watch theyve ever sold. today its worth 2x what I paid for it.
btw just noticed IWC's pilots watch is in its 16th revision, which means you can buy a
Spitfire MkXVI from them
