Movado Sphere Lock Collection , iconic modern design meets timeless style. This luxurious vermeil—14k yellow gold-plated sterling silver—chain necklace reinterprets our signature sphere—inspired by the iconic Museum Dot that symbolizes the sun at high noon—a twisting lock acts as the closure and stunning focal point. The sphere screws open to allow the chain link on and off the neck. The necklace is 16 inches long and finished with our dot tag.
