Rolex 278274-0018 Datejust 31mm Stainless Steel Jubilee Mint Green Dial Watch

Rolex Datejust 31 – Ref. 278274-0018

The Rolex Datejust 31 Ref. 278274-0018 is an exquisite example of modern elegance in women’s timepieces. Marrying Oystersteel and white gold in Rolex’s iconic White Rolesor format, it features a fluted white gold bezel, mint green sunray dial, and Jubilee bracelet for refined sophistication. With a 31 mm case, reliable in-house movement, and classic Rolex design cues, this model is ideal for someone seeking both luxury and everyday wearability.

Case Materials

This Datejust features a 31 mm Oyster case crafted from Oystersteel (Rolex’s 904L-grade steel) combined with a fluted white gold bezel, creating the celebrated White Rolesor aesthetic. The fluted bezel, a Rolex signature, was originally functional—to help screw the bezel onto the case for waterproofness—but today is also a hallmark of distinction and style. The Twinlock screw-down crown and a hermetically sealed case back help deliver 100 meters / 330 feet of water resistance.

Dial Visual Identity

The mint green dial is finished with a sunray brushing technique, creating subtle radiating lines that catch and diffuse light beautifully across the surface. Rolex achieves this through masterful brushing and PVD/electroplating before applying a final layer of varnish. Applied baton hour markers and dauphine hands offer legible contrast. Above the 3 o’clock marker, a Cyclops lens magnifies the date window for clarity. The dial detail and soft color bring personality and elegance to the piece.

Movement Performance

Under the dial is Rolex’s in-house Calibre 2236, a self-winding mechanical movement equipped with the Syloxi silicon hairspring and Chromalight luminescence. The movement is certified as a Superlative Chronometer, delivering precision of –2/+2 seconds per day after casing. It provides around 55 hours of power reserve. This caliber offers graceful performance, robustness, and Rolex’s engineering excellence.

Bracelet Wearability

The 278274-0018 comes on Rolex’s classic Jubilee bracelet, composed of 5-piece links for flexibility and comfort. It includes the hidden folding Crownclasp, which maintains a seamless aesthetic. The Jubilee is known for its supple feel on the wrist and polished finish, making it both ergonomic and luxurious.
