I was digging through some boxes in my closet the other day and found an old Heuer Autavia (purchased new by me in the mid 70's) that I recall a cinder block falling on and destroying the crystal and bezel insert. Is there any good source for these items so that I don't have to rely on the local watch shop to kill me with their price? Any and all guidance is appreciated. I never knew until I Googled Autavia what the market was for these fine timepieces!!!
