Estimate: CHF 40,000 –⁠ 80,000

The reference 6611B is, without question, one of the rarest and most distinguished Day-Date models ever created by Rolex. This particular example, dating back to 1958, stands out not only for its incredible quality but also for its distinctive features that make it so highly desirable among collectors. Powered by the caliber 1055, this watch was manufactured during the early years of the Day-Date’s release, a period when Rolex was defining what luxury timepieces could be. What makes this piece even more exceptional is the pink-gold case, with its distinctive reeded bezel, which remains very fresh even today, thanks to the careful stewardship of its previous owners. Adding to its rarity is the exquisite pink-gold "shutter" style bracelet with its fine texture, a configuration seldom seen, which truly elevates the watch's overall presence. But perhaps the most striking feature is the dial: its gorgeous black gilt surface, paired with unusually shaped “claws” gold-applied indexes, creates a visual effect that is both charming and captivating. The condition of the dial is remarkable, and even more significant is the "underline" at 6 o’clock, a mark that indicates the use of tritium luminous material, a shift from the earlier radium due to changes in watch regulation. With dauphine hands and a Spanish calendar, this is, without a doubt, a magnificent example of Rolex's craftsmanship— timeless, elegant, and rare. A true masterpiece for the discerning collector.
