Rolex Oyster, Bubble Back, yellow gold and stainless steel hooded case, rare black dial with majestic design, circa 1940s. The hooded case with a sense of gravity makes it stand out among the many variations of the bubble back, and the black Majestic dial, which is very rare among bubble back, is a gem with a taste of texture. The contrast between black and gold is also attractive. The screw-back water-resistant case with a screw-down crown, fully rotating self-winding movement, rich dial variations, and case design are all unique to Rolex of this era, which cannot be seen in other companies of the same age.
