A sleek and sporty men’s chronograph from the Lorus Sports Solar collection — the RZ509AX9 features a 43.8 mm stainless-steel case and matching steel bracelet. It’s powered by a solar quartz movement (Calibre VR42), so it charges from light rather than a battery. The black dial includes a date display, chronograph stopwatch function and a tachymeter bezel. With 10 bar (100 m) water-resistance, it’s built for everyday wear and active use.
