Family: Zenith-based36,000 vph (5 Hz)
Calibre 18 is an automatic chronograph movement from TAG Heuer based on the Sellita SW300-1, operating at a high beat of 36,000 vph. It features a modular Dubois Depraz chronograph module with a date complication, derived from the Zenith El Primero lineage. The movement is not in-house and was discontinued as TAG Heuer transitioned to its own in-house chronograph calibers.
