Rolex Datejust White Rolesor — Mint Green Index Dial | Ref. 278344RBR

The Datejust 31 in white Rolesor achieves a particular refinement through the pairing of 904L Oystersteel with 18K white gold — a combination that reads as entirely white metal to the eye while providing structural and aesthetic benefits that differ meaningfully from either material alone. Reference 278344RBR adds a further layer of distinction through a domed bezel set with 24 brilliant-cut diamonds in a grain mount, the stones selected for their collective visual uniformity and closely matched colour grades. The sapphire crystal carries a Cyclops lens over the date, and the screw-down Twinlock crown ensures 100-metre waterproofing.

Calibre 2236 — the manufacture movement underpinning all 31mm Datejust references — features the landmark Syloxi hairspring: a monocrystalline silicon component with geometry optimised through computational fluid dynamics to provide superior isochronism compared to conventional metallic springs. The movement operates at a frequency of 28,800 vph (4 Hz) and achieves a certified precision of -2/+2 seconds per day post-casing, with a power reserve of approximately 55 hours supplied by a bidirectional Perpetual winding rotor. The instantaneous date display advances cleanly at midnight without creep, and the stop-seconds function halts the balance wheel for exact setting.

The mint green dial — a shade introduced to the Datejust palette in the 2020 Basel-era releases and immediately embraced by collectors for its fresh, botanical character — carries applied gold index markers whose understated form allows the dial colour itself to serve as the primary visual statement. The five-piece Jubilee bracelet in Oystersteel, with alternating brushed and mirror-polished surfaces, terminates in the Crownclasp — a concealed folding mechanism that lies entirely flush with the bracelet profile when engaged, maintaining the watch's seamless silhouette from lug to clasp. This reference represents one of the more wearable and accessible entry points into the gem-set Datejust family.
