Description
Rolex introduced the reference 6511 Day Date in 1956, which was replaced within one year by this reference 6611. The 6611 has several important and interesting characteristics: first, its movement made great improvements over its predecessor by changing how the day display advanced. Whereas the 6511 would store up energy for only a few minutes before midnight, the effect of which was that timekeeping for half an hour or so prior to the day change-over was very poor. The movement in the 6611s stores up energy for the day advancement continuously, resulting in better timekeeping. Furthermore, its movement has a free-sprung balance with microstella fine adjustment and the 6611 is the first Rolex with “SUPERLATIVE CHRONOMETER OFFICIALLY CERTIFIED” on its dial.

Astoundingly rare original solid 18k rose gold case has the 6611’s distinctive reeded bezel, which has a different pattern from the more familiar fluted bezels used on the later Datejusts and reference 1803 Day Dates. Original screw down crown is working perfectly. Plastic crystal. Screw down case back. This case still has the bubble look to it, versus the later and sleaker 1803 cases. Dimensions are 35.5mm diameter by 12mm thick.

Original, untouched, silver pie-pan dial with applied rose gold hour markers and original rose gold dauphine hands. Date is at 3 o’clock while the complete day is displayed at the top of the dial. Dial is in mint condition.

Original automatic winding Rolex Caliber 1055 with 25 jewels and adjusted to five positions and temperature. Movement is a C.O.S.C. Certified Chronometer and is in immaculate condition and running strong.

Strap is new brown suede with rose gold plated Rolex buckle.
