For recent decades, the Rolex blueprint was clear and predictable. If you wanted a Datejust, GMT-Master, or Submariner, Yellow Rolesor (steel and 18k yellow gold) was an established, celebrated choice. But if you looked at the ultimate expedition watch—the Explorer—or the quintessential daily wearer—the Oyster Perpetual—the modern rulebook was ironclad: stainless steel only.
In recent years, Rolex turned that conservative philosophy on its head. By injecting precious metal into models historically defined by utilitarian steel, the Geneva manufacture sparked intense debate among purists while creating highly discussed references in modern horology.
If you want to see how Rolex is rewriting its own modern design rules, look no further than these two unexpected Yellow Rolesor releases.
The Explorer 124273: Disrupting 70 Years of Expedition Heritage
When Sir Edmund Hillary and Tenzing Norgay summited Mount Everest in 1953, the prototype watch on the expedition was pure, rugged steel. For nearly seven decades, the Explorer 36mm remained strictly a utilitarian, monochrome tool watch.
That changed in 2021 with the release of the Reference 124273.
By fitting a smooth 18k yellow gold bezel, gold winding crown, and yellow gold center links onto a 36mm Oyster case, Rolex created a highly polarizing release. Purists questioned whether a luxury gold accent belonged on a mountain-scaling tool watch.
Yet, on the wrist, the execution is undeniable. The warmth of the 18k yellow gold contrasts sharply with the deep black lacquered dial and signature 3-6-9 Arabic numerals, giving the classic 36mm proportions an unmistakable vintage-meets-modern appeal. Powered by the modern Caliber 3230 with a 70-hour power reserve, it proved that even Rolex’s most sacred tool watch history wasn’t immune to a deliberate touch of luxury.

The Oyster Perpetual 41 Ref. 134303: A Centenary Revival
If adding gold to the Explorer was a surprise, bringing Yellow Rolesor back to the core Oyster Perpetual line for the 100th Anniversary was a brilliant revival of a dormant tradition.
While the Oyster Perpetual hasn’t always been strictly steel, modern collectors have come to know it exclusively as the brand’s accessible steel entry point. The 2026 Reference 134303 changes the narrative by looking backward to go forward.

The Foundation
1931
Rolex launched the foundational Oyster Perpetual collection, combining the waterproof Oyster case with the self-winding Perpetual movement. Early automatic models regularly featured mixed steel-and-gold combinations.
The Rolesor Era Begins
1945
Rolex introduced the Datejust, which popularized the official two-tone Rolesor (steel and gold) look with a date function, shifting the OP line more heavily toward steel.
The Last Two-Tone OP
1995
Dedicated time-only two-tone Oyster Perpetual models, such as the 34mm Reference 14203, formally entered active production before being phased out in the 2000s, leaving the line exclusively steel for over a decade.
Celebrating 100 years since Hans Wilsdorf introduced the original waterproof Oyster case in 1926, Rolex opted against a predictable full-steel iteration. Instead, they upgraded the OP 41 with a smooth yellow gold bezel, gold crown, and two-tone Oyster bracelet, echoing those early vintage releases.
To anchor its significance, Rolex paired the Rolesor case with a new slate dial featuring subtle green pad-printed minute accents and a discrete “100 years” inscription at 6 o’clock. It takes what was once the brand’s simplest steel daily wearer and turns it into a milestone collector’s piece.

The New Design Language
Rolex actively redefines where precious metals belong in its modern catalog. By taking references traditionally locked to stainless steel for the last two decades and dressing them in Yellow Rolesor, the brand creates a new sweet spot for collectors: classic utility paired with striking contrast.
