A striking men’s solar‑chronograph built for everyday sport‑elegance: the RZ515AX9 features a ~43.8 mm stainless steel case, a black sun‑ray dial with tachymeter bezel and time‑measuring sub‑dials, and a black leather strap for refined comfort. Powered by a solar‑charged Japanese Seiko VR42 movement (no battery changes needed), and offering 100 m water resistance (10 bar), it delivers both style and performance.
