Certina Chronoolympic C-tronic 749.3754.41

The Chronoolympic line was a very successful line of chronographs in its time. In addition to the legendary Valjoux manual-winding mechanisms, this line also used rare tuning fork mechanisms. Certina used ESA 9210 mechanisms licensed by Bulova, which can also be found in, for example, the Omega Speedsonic or the Longines Ultronic. A characteristic feature of tuning fork mechanisms is a gentle buzzing and the passing seconds. The watch is enclosed in a steel Lobster case, typical of the 1970s, on an original steel bracelet, suitable for wrists up to approximately 19 cm. Despite the unknown service history, the watch is fully functional. The mineral glass and the case have scratches and normal signs of use.
