The Rolex Submariner Date 126613LB — nicknamed the "Bluesy" for its blue ceramic bezel and blue dial on a two-tone Rolesor (steel and yellow gold) case and bracelet — is the warmest and most distinctive reference in the current Submariner lineup. The combination of gold and blue gives the Bluesy a character that bridges sport and dress, making it one of the most versatile Submariners ever made.
