Rolex Explorer 36 mm 124273B1 Steel/Yellow Gold Black Rolex Explorer 36 mm 124273B1 Steel/Yellow Gold…

The Rolex Explorer is one of the most storied references in the entire Rolex catalogue, born from the brand's partnership with high-altitude mountaineering expeditions and forever associated with the first successful ascent of Mount Everest in 1953. The Explorer line distills watchmaking to its essentials — legibility, reliability, and quiet authority — making it a perennial favourite among collectors and everyday wearers alike. Reference 124273B1 represents the modern 36mm generation of the Explorer, a size that pays homage to the original proportions that made the model legendary.

What sets reference 124273B1 apart from the standard steel Explorer is its Rolesor construction: the case and Oyster bracelet are crafted in Rolex's proprietary Oystersteel, while the bezel and select bracelet elements are rendered in solid 18k yellow gold. The yellow gold domed bezel — smooth and polished — adds a layer of warmth and dressy elegance that transforms the Explorer from pure tool watch into a versatile luxury companion. This two-tone configuration occupies a distinctive niche, appealing to collectors who want the Explorer's legendary DNA with a touch of precious metal distinction.

The black dial of the 124273B1 is quintessential Explorer: high-contrast white luminous hour markers at 3, 6, and 9, Mercedes hands coated in Chromalight, and the signature 'Explorer' script beneath the crown logo. The result is a dial that is instantly readable in any light condition — a design philosophy rooted in real-world adventure rather than mere aesthetics. Every element on the dial is purposeful, a hallmark of Rolex's relentless commitment to function.

Powering the watch is Rolex's automatic movement, a self-winding calibre housed in the iconic Oyster case that provides 100 metres (330 feet) of water resistance. The Oyster case, sealed by a screw-down crown and case back, is one of the most robust and tested watch cases ever produced, ensuring that the Explorer 124273B1 is as capable on the wrist as it is beautiful. The movement benefits from Rolex's Superlative Chronometer certification, guaranteeing precision to industry-leading standards.

On the wrist, the 36mm diameter strikes a timeless balance — large enough to command presence, compact enough to slip beneath a shirt cuff and transition effortlessly from the boardroom to an outdoor weekend. The Oyster bracelet, with its three-piece link construction and Oysterclasp, hugs the wrist securely and comfortably, while the yellow gold accents catch the light in a way that few two-tone sports watches can replicate. This is a watch that wears as well on a mountain trail as it does at a formal dinner.
