Rolex Day-Date 6611B
$11,569
The very first Day-Date references, the reference 6510 (with a domed bezel) and reference 6511 (with a fluted bezel) were introduced in 1956. They were produced for a single year before being fitted with an upgraded movement. The next generation, references 6611, 6612, and 6613, contained an upgraded version of the calibre 1055.
The upgrade included a new balance wheel with microstella regulating screws. The new movement received a certification from the Official Swiss Chronometer Testing Institute (C.O.S.C.). On this references we see the text 'Superlative Chronometer Officially Certified' for the very first time on a Day-Date. The previous ones had 'Officially Certified Chronometer' on the dial.This is a unique example of the Rolex Day-Date: the reference is 6611 B, which is already quite rare.
This Day-Date has a very classic configuration with a champagne pie pan dial, an 18k yellow-gold index and dauphine hands. It comes on a leather strap with a Rolex buckle.
