With its refined dial, it perfectly captures the style and unique charm of the era. The 30 mm case diameter reflects the standard size for men's watches of the time, enhancing its authentic vintage appeal.
While many 1940s Oyster Royal models feature restored dials, this example stands out with a fully original, unrestored dial. The applied hour numerals retain their original radium lume, which has developed a beautiful, even patina over the decades - a true vintage collector's dream.
Another rare detail is the original Rolex crown with the radial "Oyster Patent" engraving - a signature feature of early Oyster models and a detail rarely seen today.
