About the Item

Rolex Datejust Ref. 1601, Mosaic Blue Dial, Steel 18k White Gold, Full Set, 1977 (5.1M Serial, JDM) Among vintage Datejusts, few dials capture collectors’ imaginations like the Mosaic Blue. Produced in limited numbers and primarily for the Japanese domestic market, this dial is highly coveted for its unique texture and vibrant play of color — an unmistakable departure from the standard Datejust aesthetic. This reference 1601, bearing a 5.1 million serial dating to 1977, features a 36mm stainless steel case with 18k white gold fluted bezel, paired with its original steel bracelet. The Mosaic Blue dial remains the centerpiece, its intricate pattern and deep blue tone shifting beautifully with the light, offering both rarity and refined charm. Powered by Rolex’s automatic movement and recently serviced, this piece is offered as a complete set with both original box and papers — a particularly scarce find for a watch of this era. At 86.1 grams and 18cm in length, it is in excellent condition and ready to be enjoyed by the discerning collector. The combination of the Japanese-market dial, complete provenance, and classic Datejust architecture makes this watch an exceptional and highly collectible example of Rolex’s design legacy in the late 1970s. At Classic Time Club, we handpick every watch for its superb condition, design excellence, and timeless appeal.
