This is a brand new, domed plexiglass for Heuer Autavia chronographs models that take a domed plexi (that is to say, for ALL Autavia Ref. #s EXCEPT Ref. 11630 & 11603). They are GS diver-tite double thick deep-sea pressure proof plexis with a tension ring. Autavias with Ref. 11630 & 11603 take a mineral glass (flat or domed) and these are listed separately in our store. It is not a NOS Heuer product, but a suitable replacement plexiglass for your watch. The listed price is for one domed plexiglass and does not, of course, include any watch you see in this listing, which is shown for presentation purposes only.
Feel free to contact me for whatever questions you might have and remember that I do not accept returns for such parts.
