The Rolex Datejust Reference 1601 in solid 18K yellow gold paired with a silver "step" dial is an incredibly desirable, investment-grade vintage timepiece. Produced primarily between 1960 and 1981, the reference 1601 is iconic for its classic 36mm proportions and its distinct mid-century design architecture.

  While the reference 1601 is most commonly seen in stainless steel or steel-and-gold two-tone configurations, a solid 18K yellow gold iteration drastically increases both its rarity and market value. 

  Furthermore, the "Step" dial is highly coveted because Rolex moved away from this sloped design toward completely flat dials in subsequent generations (like the reference 16030 or 16233). Finding one in "Mint" condition—meaning the lugs are still thick, the fluted peaks on the gold bezel remain sharply defined, and the original tritium lume plots are intact without degradation—makes it a true collector's piece.

• Case Size: 36mm diameter (approx. 44mm lug-to-lug, 20mm lug width).

• Material: Solid 18K yellow gold case with a sharp, matching fluted bezel.

• Dial Architecture: Silver "Step" Dial (often referred to by collectors as a "Pie-Pan" dial). It features a sloped outer minute track that slopes downward, giving the watch face immense visual depth.

• Movement: Rolex automatic, self-winding mechanical movement (historically powered by the ultra-reliable Caliber 1565 or 1575).

• Bracelet: Solid 18K yellow gold Jubilee bracelet.

• Crystal: Vintage acrylic (Plexiglass) featuring a Cyclops magnification lens over the date window.
