The Date, Datejust and Day-Date models have historically been a creative canvas for Rolex, used to express new designs and materials to an extent not even remotely approached by other models. The present piece perfectly exemplifies this concept: a true interpreter of the spirit of the 1960s and 1970s, the entire aesthetic impact of the piece is entrusted to the textured case and bracelet, while the dial remains relatively clean and free of clutter and scales. This trend was typical of the time, until the mid 1980s.

This Ricciardi retailed example not only impresses with its overall condition - most notably, the Ricciardi numbers stamped underneath the lugs are absolutely unmolested, and the case has acquired a warm layer of oxidation over the years - but also with the presence of the original Guarantee booklet dated September 8, 1969 and even of the COSC certification.

It is intriguing to note how all Zephyr 1510 examples feature a quirky detail: while the dial is marked T Swiss T, there is no trace of luminous material. This is most probably the result of Rolex employing for this reference pre-existing clichés bearing the T Swiss T designation.
