Hey,
Well - I had the same dilemma about 10 years ago - I needed a new bezel for my Autavia and some other bits - they didn't make them any more etc.. BUT if you are into the game for the long haul then you shouldn't worry.. We now have the internet that allows you to track down the most obscure things given enough time.. Eventually Alex from this forum broke up an Autavia with a bezel exactly as I needed - not cheap - but worth it to bring my Lovely 11630MH back to its former glory.. Autavia bezels do come up on the dreaded eBay from time to time - just make a search for AUTAVIA BEZEL and save it so they email you every time something matches the description - or give Alex an email to see if he has the bezel you require - the website is http://www.heuerautavia.com/
Warren..
