Rolex Datejust 31 Everose Rolesor — Silver Diamond Dial | Ref. 278241

Reference 278241 represents the contemporary expression of the Datejust 31, a size introduced to bridge the gap between the full 36 mm case and the Lady-Datejust 28. In Everose Rolesor — Rolex's proprietary blend of 18 ct Everose gold combined with Oystersteel — the watch presents a warmly luminous case profile that flatters a wide range of wrist sizes. The silver dial set with a diamond hour track catches light with quiet brilliance, each stone precisely set in 18 ct gold to resist displacement even under daily wear.

The 278xxx reference generation is powered by the Calibre 2236, Rolex's purpose-built movement for the mid-size Datejust family. This self-winding calibre incorporates a Syloxi hairspring machined from silicon, granting exceptional resistance to temperature variation and magnetic interference. With a power reserve of approximately 55 hours and certified Superlative Chronometer status, the 2236 delivers the precision one expects from Geneva's most meticulous manufacture. The case is fitted with a scratch-resistant sapphire crystal and maintains water resistance to 100 metres via the Twinlock crown system.

The 31 mm Datejust has steadily grown in collector appeal as the horological market recognises the technical distinction of the Calibre 2236 platform. The Everose Rolesor configuration is particularly prized for its visual warmth without the full commitment of a solid gold case, making it a practical daily companion that nonetheless registers as a serious luxury object. Diamond-dial variants consistently hold their secondary market value, and the 278241 in this configuration is regarded as one of the more refined expressions currently available in Rolex's ladies' and mid-size offering.
