Be it in the greater world of watches or just within the context of Rolex, the Explorer is a known quantity. It's long-standing, straightforward, and, even among its much-loved siblings, it is iconic. The Explorer is one pure unit of Rolex sport watch. The Explorer's timeline establishes it as a category-defining model, and while the Explorer has evolved over the past half-century, the core formula is one of everyday versatility, thoughtful simplicity, and steadfast reliability. This remains true from its mountain-top roots to several fun and collectible references that emerged over the decades. Today's Rolex Explorer is officially known as the 214270, but from remote Himalayan peaks to a Midtown boardroom or a weekend in the backyard, we all know it just as the Explorer.
