The TAG Heuer Calibre 8 is a Swiss made automatic movement based on an ETA caliber 2892-A2 with a Soprod TT651 module for the grande date and dual time subdial. This is movement is a certified chronometer (by COSC). Most, but not all of the cal. 8 movements feature Côtes de Genève decorating on the rotor, which is also engraved with TAG Heuer / Calibre 8 / Swiss Made.
In TAG’s own words:
“All TAG Heuer automatic movements are made in Switzerland and must meet extremely strict criteria for precision before they make it onto your wrist. Their high frequency ensures excellent mechanical precision. A number of TAG Heuer automatic movements are awarded an Official Swiss Chronometer Control (C.O.S.C.) Certificate, the ultimate recognition of precision and reliability.”

You may still be able to find new old stock timepieces from ADs or you could certainly find pre-owned watches with this movement.
