Yeslam Aviator III Watch

At the confluence of aviation and watchmaking, Yeslam is proud to present its latest creation, Aviator III, a watch designed by and for pilots. Its particularity is that it can calculate the speed of an object in relation to the speed of sound (Mach). Its many other attributes include an automatic movement with alarm and dual time zone, a rotating bezel made from cobalt, a titanium case and a calfskin strap whose elegant perforations confirm the aviator style. With this new product, Yeslam cleverly combines two domains in what is both a timepiece and a flight instrument; two distinct worlds with precision and excellence as their common denominator.
