The 28mm case of this Rolex Lady Datejust 279178-0009 is the benchmark for durability and reliability. The crown is tightly screwed to the case. On the gold dial, white diamond watch indices emit brilliance. Rolex guarantees the following characteristics when wearing a Rolex watch: high precision, automatic winding, water resistant to 100 meters and a power reserve of 55 hours. One of the special features of the Rolex datejust is the very smooth movement of the second hand. Above the date aperture, there is a cyclop lens. The watches are completed with an elegant five-row Rolex bracelet made of 18-carat yellow gold.
