Those who don't want to give up the advantages of our great chronographs but would like a smaller case will love the Model 256 series, which has a diameter of 38.5 mm. The driving force behind the 256 series is the proven Valjoux 7750 automatic movement.
Our model 256 Ty is perfect for those who love fast cars. The classic tachymeter scale – originally designed for setting the automobile tachometer for calibration routes set up especially for that purpose – is engraved on the stainless steel outer ring and facilitates speed measurements from 60 km / h to 500 km / h.
