I recently noticed the Autavia Isograph line is no longer on the Tag Heuer website. I just talked to my AD and he said Tag Heuer is quietly pulling all the Autavia Isographs off the market. I think they were having issues with production of the Isograph. They will likely relaunch the Autavias next year without the Isograph technology. I'm so happy I acquired one with the Isograph (but I hope I don't have any issues with it in the future). These might become more rare than an albatross. They were hardly available at all.
