1940s Rolex Oyster Bubble Back, Steel, Black-Unique Dial With Rare Sub-Seconds

Rolex Oyster, Bubbleback, stainless steel, black dial with roman and arabic indexes, rare sub-seconds feature, circa 1940s. The Black Unique and Sub-Seconds model is the most popular and rare of the Unique dials. Compared to the center-seconds model, there are far fewer of them produced, and it is extremely rare to find a well-preserved one on the market, especially one that retains the beautiful black mirror luster and the original radium luminescence. The rare two-piece case with the same unique number engraved on the back cover and middle case is a gem that further enhances the rarity of this piece. It is equipped with a precious Gayfreres expansion tapered bracelet.
