: Minor thing, but its a Heuer Autavia, not a Tag Heuer. The original
: company was called Heuer and yours is from the 70's before they
: became Tag Heuer. Its a nice looking watch, the pusher needs to
: be replaced and the bezel appears incorrect. Finding the missing
: parts could become a challenge. There are many competent
: watchmakers, If you are in the US- I would check with Craig with
: ChronoDeco, Jack at International Watch Works or Phillip at
: Watchmakers International. All are brilliant watchmakers, but
: highly unlikely any of them will have the parts you need. I
: believe Swiss Watches and More has the correct pusher, but it
: can be difficult to order. You can also watch eBay, they
: sometimes appear. Just have to be careful to get the correct
: version.

: Servicing vintage Hauers can be a challenge as the parts are
: coveted and hard to source. Fortunately this is one of the more
: common of the vintage Heuers, so will be the easiest to find if
: you are patient.

Are the pushers the same for the 11 and 12 movement? Do we need to know the case, or anything else??
