TAG Heuer 2894-2 Automatic Bi-Compax Chronograph Watch Movement


Despite the similar base, TAG Heuer has chosen not to call this movement Calibre 17 like the other 2894-2 that he uses for their chronograph models. Instead they went for a gold tone oscillating weight, and used this variant to power their HEUER MONACO CS2110 models and many of the classic bi-compax Carrera re-editions.
