Rolex Day-Date 36mm Black 1807

Rolex Day-Date Ref. 1807 — Pink Gold “Bark” Case

Ultra-Rare Vintage Collector’s Piece (1965)

Among vintage Rolex Day-Date references, rarity is often defined by the dial. With the reference 1807, however, Rolex went far beyond the dial — transforming the case and bracelet into works of art. The 1807 represents one of Rolex’s most distinctive and experimental executions, elevating the Day-Date into a true collector’s icon.

Introduced in the 1960s as a variation of the classic 1803, the Day-Date 1807 features Rolex’s legendary “Bark” finish — a hand-engraved texture inspired by tree bark, applied to the bezel and bracelet center links. This artisanal detail is exceptionally rare within Rolex’s otherwise industrial production philosophy. Produced in yellow, white, and pink gold, the pink gold examples are by far the rarest, appearing only on exceptional occasions.

This remarkable example dates to 1965 and is preserved in outstanding condition. The 18k pink gold case remains sharp and well-defined, with a prominent bark bezel contrasting beautifully against the matte-finished lugs. Even more exceptional, the watch retains its original South American pink gold riveted expandable Oyster bracelet — complete with Portuguese import hallmarks on the clasp, blades, end links, and case back. With 12 links, spring-loaded elasticity, and minimal wear, the bracelet is an extraordinarily rare survivor after nearly six decades.

The color of the pink gold is another defining feature. Unlike many vintage pink gold Rolex watches that fade toward yellow over time, this piece retains a deep, vibrant pink hue. This tonal variation reflects Rolex’s evolving pink gold alloys during the 1960s, making each surviving example visually unique.

Complementing the case is an exceptional black glossy lacquer dial reminiscent of Stella finishes. The dial features pink-toned printing, intact luminous plots aged to a warm brown, and hands perfectly matched in tone. Champagne-colored Portuguese day and date discs confirm that the watch was originally manufactured for the Brazilian market — further enhancing its historical significance.

The result is a dream configuration: vivid pink gold, hand-engraved bark bezel, rare expandable Oyster bracelet, and a glossy black lacquer dial. More than a watch, this is a statement of artistry, heritage, and rarity. After many years in a private collection, this extraordinary Day-Date is now offered to its next custodian — a once-in-a-lifetime opportunity for serious collectors.
