"Los detalles son lo mas importante".

The Rolex Day-Date is a watch of many firsts. For instance, it was the first watch to display the day and date, written out in full on the dial. And, it did so whilst being self-winding and waterproof to boot. The very first Day-Dates, the ref. 6510 and 6511, were introduced in 1956 and saw production for only a year. In 1957 they were replaced by the 66XX series Day-Dates. This upgraded model is an important milestone in Rolex as it was the very first Day-Date, and one of the very first Rolex watches, to receive the highest chronometer certification from the Official Swiss Chronometer Testing Institute (COSC), a fact that has been proudly printed on Rolex dials ever since.

This beautiful ref. 6611B is a very early Day-Date, from 1958 to be precise. The 36 mm Oyster case is executed in 18k yellow gold and features an early version of the iconic fluted bezels. As these bezels contained a finer and narrower pattern, collectors often refer to them as "coin edge" or "milled" bezels.

This specimen features the original grainy dial that remained very much in-tact, regardless of the radioactive luminous material under the elegant markers and in the leaf-hands. Most importantly it features a retailer stamp: Serpico Y Laino. So this watch was sold in Caracas by the most historically important retailer of Venezuela, hence the Spanish day disc, the import stamp on the caseback and the D'Agosto Jubilee bracelet. The topside of the clasp, proudly displaying the big logo coronet, has a jaunty engraving of the first owners initials.

This rare and collectible Day-Date, from arguably the most stylish period for the flagship model, remains in very fair condition and is as attractive as it was when it left the factory 65 years ago; or perhaps even more.
