Achieving superb performance worthy of the prestigious Superlative Chronometer certification and offering the reliable durability associated with the brand, this astonishing timepiece from Rolex boasts a masculine appearance and a pleasing tone set by the metallic gleam of gold and attractive nuance of the dial contributing to the classic racing spirit. Comprised of a monobloc middle case, screw-down back and crown with Triplock triple waterproof system, the 40mm 18K white gold case also features scratch-resistant sapphire crystal held firmly by the fixed 18K white gold bezel to ensure 100m water resistance. Inside, the 4130 features blue Parachrom hairspring and builds up approximately 72 hours of power reserve through its bi-directional self-winding via Perpetual rotor. Displaying hours and minutes via luminescent central hands, the blue dial allows great legibility through smart contrast and luminescent hour-markers, boasting also small seconds at six o’clock as well as chronograph central seconds with 30-minute and 12-hour counters at three and nine o’clock respectively, while tachymeter scale is engraved on the bezel. The watch is worn on a three-piece link 18K white gold bracelet with Oysterlock folding safety clasp and Easylink system for extension up to 5mm
