Rolex 4645

An extremely rare and very early, Cioccolatone, automatic wristwatch in pink gold, with star index dial, reference 4645.

Model Cioccolatone Reference 4645 Case Material Pink gold Bracelet Material Leather strap Year 1951 Movement Automatic, 2 jewels Case N° 668'806 Dimensions 30mm width x 30mm length Signed Case, dial and movement Nicknamed “Cioccolatone” for its resemblance to a block of chocolate, this square-shaped timepiece stands out among Rolex’s offerings for its elegant yet understated aesthetic. The reference is notable for being one of the few models from the brand that features a self-winding movement outside of the iconic Oyster case, and this specific watch is one of the very first “Officially certified chronometer” which have ever obtained this specification and it proudly shows it on the dial at 6 o’clock. The case is crafted in 18k pink gold, a rare and refined material, adding to the watch’s charm. The brushed silvered dial features applied gold hour markers, with the signature “12” in Arabic numerals and a small seconds subdial. What truly sets this particular example apart is the presence of two “star” indexes at the 3 and 9 o’clock positions, a detail that is incredibly rare and highly prized by collectors. These star-shaped markers lend an added touch of luxury and distinction, making this timepiece not only an excellent example of mid-20th-century Rolex craftsmanship but also a highly desirable piece among collectors. The “Cioccolatone” is famed for its distinctive square-shaped case with stepped sides and straight lugs, which are beautifully preserved in this particular example, exuding a wonderful vintage appeal. The combination of the rare star indexes and the 18k pink gold case makes this “Cioccolatone” a standout addition to any serious watch collection, representing an era when Rolex was exploring creative design solutions beyond its iconic round Oyster cases.
