The ETA 7750 movement, also known as the TAG Heuer Calibre 16, is perhaps the most successful automatic chronograph movement ever produced. While it has become fashionable to regard the 7750 as a generic, common movement, the calibre is easily able to meet COSC Chronometre standards (in top spec) and can be found in a range of high-end watch brands, including IWC, Tudor, Panerai, Hublot and, of course, TAG Heuer.
