Introduced in the late 1950s, the Rolex Datejust 1601 emerged as a symbol of post-war optimism, marrying the brand’s pioneering Oyster case technology with the glamour of precious metals. This particular example, crafted during the 1960s–1970s, showcases the model’s most coveted features.

The 36mm stainless steel Oyster case—meticulously engineered to withstand 50 meters of water resistance—is crowned by an 18K yellow gold fluted bezel, a design originally inspired by the cogwheel of a mechanical movement. This bezel, machined with Rolex’s signature engine-turned grooves, catches light like a faceted gemstone, creating a dynamic interplay with the dial.

The mother of pearl dial is a triumph of natural artistry. Sourced from the inner layers of iridescent mollusk shells, each dial is a unique masterpiece, exhibiting delicate veins and a spectrum of hues from silver to pale pink under shifting light. While this example features an aftermarket dial, it closely echoes Rolex’s own high standards—free from cracks or imperfections. If diamond hour markers are present, they are set in 18K gold, adding a layer of understated luxury. Their brilliance contrasts beautifully with the dial’s organic texture.

Powering this watch is the Rolex Caliber 1570, a movement celebrated for its robustness and precision. Introduced in 1965, this 26-jewel automatic movement features a free-sprung balance, a Microstella regulation system, and a bidirectional rotor for efficient winding. Though it lacks hacking seconds (a deliberate design choice to reduce wear), its chronometer certification ensures accuracy within -4/+6 seconds per day—a standard that rivals modern calibers.

The acrylic crystal, with its domed profile and classic Cyclops magnifier, offers distortion-free viewing while lending a warm, vintage glow to the dial beneath.

Finally, the watch is mounted on a hand-stitched leather strap, likely added during its lifetime. Crafted from full-grain calfskin or exotic hide, the strap's gentle patina and suppleness suggest careful selection. Paired with a stainless steel tang buckle, it offers secure and comfortable wear. Though the original two-tone Jubilee bracelet is not included, this configuration channels the era’s preference for understated, adaptable elegance—suitable for tailored formalwear or relaxed weekend attire.
