Replica Rolex Lady-Datejust 178240 31mm Blue Dial

The 31mm Lady-Datejust occupies the middle ground between the compact 26mm and the larger 36mm Datejust, and the 178240 in blue makes a strong case for why this size works so well. Large enough to read easily and display the dial’s colour with impact, yet small enough to maintain the delicate proportions expected of a ladies’ reference. In full Oystersteel with a smooth bezel and Oyster bracelet, this is the sportiest interpretation of the Lady-Datejust family.

Key Specifications

The 178240 Blue Up Close: Case, Dial and Bracelet

The blue sunburst dial radiates from centre to edge with a finish that transitions from near-navy in shadow to a brilliant royal blue in direct light. Applied stick markers in Oystersteel carry luminescent fill for nighttime reading, and the date window at three o’clock benefits from Cyclops magnification. The overall effect is a dial that feels vibrant yet professional.

The smooth steel bezel creates an unbroken visual line from case to dial, giving the 178240 a sleek appearance that distinguishes it from fluted-bezel models. The Oyster bracelet with three-piece links and Easylink micro-extension provides secure, comfortable wear throughout the day. View all mid-size options in the Lady-Datejust collection.
