This episode introduces the upcoming Super-COSC certification, a new standard for Swiss watch precision set to launch in September 2026 by the Contrôle Officiel Suisse des Chronomètres.

This initiative is a response to tighter, proprietary accuracy standards already established by brands such as Rolex and Omega, effectively raising the industry benchmark beyond the traditional COSC chronometer designation.

Key changes in Super-COSC include significantly reduced daily deviation limits, mandatory testing of the finished watch rather than just the movement, and expanded criteria covering factors like magnetic resistance and power reserve verification.
