The Rolex Day Date, also known as the "Rolex President", is a legendary and highly prestigious model in Rolex's rich history. Unlike the so-called "sports" models, the Rolex Day Date is a pure luxury product. Always produced in white, yellow or rose gold, it is perfectly suited to everyday use, thanks in particular to its day and date functions, which are all too often neglected. The 18238 saw the introduction of the quickset for the day in addition to the date, providing a practical advantage without compromising the watch's vintage aesthetic. 
A description of the Day Date would be incomplete without mentioning the feature that sets it apart from the rest: the iconic President bracelet. The fact that a model is named after its bracelet speaks for itself.
This particular piece is in fantastic condition, including the rare blue vignette dial, which is immaculate. Indeed, many of the vignette dials on the market are unfortunately fakes. This dial is the main attraction of this piece, shifting from royal blue to a deep navy blue at the edges, all with an extremely well-executed gradient. As seen on the second picture, the way the lacquer has been laid out gives deeper reflections than on a more standard sunburst dial.
What's more, this piece has been preserved in super cosmetic condition. Both the bracelet and case are in excellent condition. It is a perfect collection timepiece.
