The Rolex Cookie Monster is one of the most distinctive modern interpretations of the Submariner. Defined by its striking combination of a black dial, blue Cerachrom bezel and white-gold case and bracelet, it has become a highly recognisable and sought-after configuration among contemporary Rolex collectors.

The story began in 2008 with the ref. 116619LB, the first white-gold Submariner Date to feature Rolex’s blue Cerachrom bezel. Originally introduced with a blue dial, the model was nicknamed “Smurf” by collectors, inspired by its distinctive all-blue appearance. In 2020, Rolex discontinued the 116619LB and introduced a new generation of white-gold Submariner Date models.

The ref. 126619LB marked a significant change, replacing the blue dial of its predecessor with a black dial, while retaining the distinctive blue Cerachrom bezel. This combination of black and blue led collectors to adopt the nickname “Cookie Monster,” referencing the familiar blue character from Sesame Street. The model is powered by Rolex’s next-generation Calibre 3235 movement and features the larger 41mm Submariner case introduced with the new generation.

The Cookie Monster is a collector nickname rather than an official Rolex model name. The 126619LB combines the technical evolution of the modern Submariner with an unusual and highly recognisable colour configuration. Its white-gold construction, black dial and blue ceramic bezel give it a distinctive presence within the current Rolex collection.

Together, the 116619LB and 126619LB represent an important chapter in the evolution of Rolex’s white-gold Submariner Date. From the all-blue Smurf to the black-and-blue Cookie Monster, these references demonstrate how subtle changes in colour and configuration can create some of the most memorable modern Rolex designs.
