Valjoux 236

Higher-beat replacement for the Valjoux 23, operating at 21,600 vibrations per hour. Produced from 1974 to 1979. Features the same 9-column wheel design but without the 12-hour counter (only 30-minute counter at 3 o'clock and small seconds at 9 o'clock). Like the Cal. 726, the increased beat rate provided improved accuracy. Short production run as the quartz crisis and transition to the 7750 series limited its output.
