Since its introduction in 1956, the Rolex Submariner has evolved into a highly versatile timepiece. Instantly recognizable, the Submariner boasts a 40mm stainless steel Oyster case outfitted with a blue and gold bezel and a matching Serti dial set with diamonds and sapphires. The bezel offers a unidirectional design for safe timekeeping while diving far below the surface of the ocean. The case is also accompanied by a scratch-resistant sapphire crystal and a waterproof Triplock screw-down crown, making this reference the ultimate underwater tool. Luminous hour markers and sweeping hands provide a highly visible reading for increased functionality while diving. Stainless steel and 18 karat yellow gold adorn the case, Oyster bracelet, and folding Oysterlock clasp, creating the perfect companion while on land or at sea.
