The reference 4500 produced by Rolex between 1946 and 1947 is an innovative creation for Rolex given its totally new design of the case, compared to the previous ones, with straighter and more pointed lugs that will then be the basis of many subsequent models. Moreover, this model is one of the very rare chronographs in an Oyster case to feature only two counters, one for constant seconds and one for the 30 minutes, omitting the 12 hours register. The two body case of the reference was available in stainless steel, pink gold, steel and gold, and, such as the present example, in yellow gold. The presence of only two registers on a very well preserved dial, as previously said, makes the quadrant and the whole watch looking smoother, elegant and a bit less sporty. The argentè background presents a seductive patina while there are two main peculiarities that makes the present lot extremely desirable. First of all, the blue pulsation scale that runs over the border of the dial, one of the only very few seen on the market at the moment. Secondly, the fancy and rare personalization for Joyeria Riviera, important Cuba-based jewelry. Located in the luxury “Galiano Boulevard” in Havana, Joyeria Riviera was part of the very few retailers allowed to have their name printed on the dial underneath the Rolex and model’s name. The watch further comes with a Rolex letter sent directly to Julio Abislaiman, president of the Joyeria Riviera in San Juan, Puerto Rico, stating the amount of production for the reference 4500 in various materials: 200 in steel, 100 in steel and pink gold, 36 in pink gold and 12 only in 9 kt yellow gold.
