Replica Rolex Lady-Datejust 178240 31mm Black Dial

Among the Lady-Datejust references that favour understated elegance, the 178240 in full Oystersteel with a black dial stands out for its versatility. The monochrome palette — black dial against polished steel with a smooth bezel — creates a watch that transitions seamlessly from office to evening. At 31mm, the ref. 178240 occupies the mid-size sweet spot in the Lady-Datejust range, offering a presence that reads clearly on the wrist without overwhelming smaller proportions.

The 178240 Up Close: Case, Dial and Bracelet

The black dial provides high contrast against the applied Oystersteel stick hour markers and hands, both filled with luminescent material for low-light legibility. A date window at three o’clock is magnified by the Cyclops lens mounted on the flat sapphire crystal. The smooth domed bezel gives the watch a clean, sporty character compared to fluted alternatives.

The Oyster bracelet with its three-piece links offers a robust, comfortable fit with the Easylink extension system allowing quick adjustment. The 31mm case sits naturally on most women’s wrists while maintaining readability. Explore the full range of Lady-Datejust options in the Lady-Datejust collection.

Movement Options: Swiss vs Japanese

Two movement tiers are available, allowing you to choose the level of horological refinement that suits your priorities:

• Swiss automatic — higher beat rate producing a smoother seconds sweep, extended power reserve, and finishing that closely follows the genuine caliber architecture. Ideal for collectors who value precision.
• Japanese automatic — reliable Miyota-based movement with proven durability and easy worldwide servicing. An excellent entry point with dependable daily performance.

Both options include quickset date adjustment and hacking seconds for precise time setting.
