Rolex's Day-Date remains the brand's signature calendar watch, and this reference 118138 brings that lineage into a warm 36mm yellow gold case with a rich green dial. The pairing feels more nuanced than traditional champagne, giving the watch a distinctly modern edge without straying from the model's formal roots. Its automatic movement drives the calendar and date display with the straightforward utility collectors expect from a Day-Date. At 36mm and 12.3mm thick, it wears with the balanced proportions that define the line.
