Blue dials and steel cases have a natural chemistry — the cool tones of Oystersteel amplify the depth of a blue sunburst finish rather than competing with it. The Lady-Datejust 178240 in blue pairs a smooth bezel and full Oystersteel case with a Jubilee bracelet at 30mm, creating a compact watch that brings colour to the wrist without the warmth of gold. For buyers who want a modern, casual Lady-Datejust with personality, this configuration delivers exactly that.

The 178240 Blue Dial Up Close
The blue sunburst finish radiates from the centre with fine brushed lines, shifting from a mid-blue under diffused light to a deeper navy at the edges and a vivid royal blue in direct sunlight. Applied stick markers in Oystersteel carry luminescent fill, standing out clearly against the saturated background. A date window at three o’clock is magnified by the Cyclops lens.
The smooth steel bezel provides a clean, unadorned frame that keeps visual focus on the colourful dial. The Jubilee bracelet in full Oystersteel adds a dressier feel than the Oyster option, draping softly with its five-piece link design.
