The caliber B130 is an adaptation of the venerable ETA 2894-2. This movement is not to be confused with older ETA chronographs like the 2892, which link use link a horizontal clutch and cam actuator derived from the Valjoux 7750. Notably, link the 2894-2 uses a very thin (and somewhat unconventionally shaped) column wheel actuator and vertical clutch, which together produce precise clicks and positive engagement for the chronograph functionality.
