About the watch
The Rolex Datejust 1601 in steel and rose gold presents itself in a particularly balanced and uncommon configuration, where the warm tones of rose gold interact naturally with the neutrality of steel, never feeling forced.
The slate-grey dial is the true highlight of this piece. Its radial satin finish creates subtle shifts between grey and anthracite depending on the light, offering depth without becoming overpowering. The applied indices and rose gold hands stand out with restraint, adding warmth and chromatic coherence to the overall composition.
The fluted rose gold bezel frames the dial with a soft brilliance, less assertive than yellow gold. The steel case maintains clean, well-defined lines, while the two-tone Jubilee bracelet enhances the watch’s fluidity on the wrist, alternating satin and polished surfaces with effortless harmony.
The 36 mm proportions remain perfectly faithful to the Datejust aesthetic: versatile, balanced, and timeless. The plexiglass crystal and the slightly “pie-pan” dial profile contribute to the visual softness typical of vintage models.
The sigma dial adds an additional layer of interest. The small σ symbols flanking the “Swiss” signature indicate solid gold indices—a technical detail that also translates into a richer aesthetic, perfectly aligned with the rose gold bezel and bracelet.
In excellent overall condition, this example shows very convincing preservation: a clean, even dial, well-defined indices, a case that retains its proportions, and a bracelet with strong presence. Overall, a Datejust that emphasizes harmony of materials and quality of detail over immediate visual impact.
Know your watch
Founded in 1905, Rolex has built its identity around technical innovation and aesthetic continuity. The Datejust, introduced in 1945, was the first automatic wrist-chronometer with an instantaneous date-change, quickly becoming a benchmark of the collection.
Reference 1601, produced between the 1960s and 1970s, represents one of the model's most classic expressions: a 36mm Oyster case, fluted bezel, and plexiglass crystal. Configurations like this one, in steel and rose gold with a sigma dial, reflect the maison's ability to interpret an iconic design into rarer and more refined variations, always maintaining stylistic coherence and construction quality.
