Thrilling to behold, this men's chronograph watch from the Master collection by Longines reveals the automatic movement through the transparent case back, while the blue dial includes a moon phase display, three subdials and traditional blue hands and painted indexes. A scratch-resistant sapphire crystal tops the 40mm stainless steel case that has water-resistance to 30 meters. The stainless steel bracelet secures in place with a fold-over deployment clasp with safety.
