Reference 6511 must be considered one of the most important Day-Date models ever produced and was cased by Brevet in either yellow or rose gold, it exclusively featured a red date wheel with “DAY-DATE” text, and used either dauphine or alpha hands. The Day-Date story begins in 1956 with the ref. 6510 and 6511. Those models laid the foundations of the Day-Date everyone knows to this day: They were the first watches to display the date and day of the week spelled out fully. The present watch was manufactured in the early years of the introduction of the Day-Date, specifically in 1956 and its yellow-gold case is still fresh as it was in that period thanks to the carefulness of the last owner. The tonneau case with screw back and reeded bezel also has a precious dial turned to a grey color with a great patina and completed by applied hours indexes. Without luminous dots at the hour markers like many other variations of the Rolex Day-Date such as the leaf hands while the calendar is in Portuguese. Moreover this lot is equipped with a rare yellow gold “BIG LOGO” bracelet. This legendary reference is very rare to find, because it was replaced within 1 year by the refs 661x.
