From Rolex, presenting the Day-Date 36 (ref. 18078 Vignette Blue), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in yellow gold and measuring 36 mm in diameter, defined by a round silhouette. The caseback is closed, and the crystal is sapphire, delivering water resistance to 10000 meters. At a glance, the dial balances texture and clarity: a blue tone, framed by gem-set indexes hour markers, and stick hands. Among collectors, it is nicknamed "Vignette". At its heart beats a proven engine: the 3055 caliber. Introduced in 1981. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
