Rolex Day-Date 40 18ct Yellow Gold — Green Ombré Diamond Bezel | Ref. 228348RBR

Reference 228348RBR is among the more visually dramatic expressions of the Day-Date 40 — a combination of an 18ct yellow gold case, a diamond-set bezel, and a green ombré dial that transitions from deep forest tones at the periphery to a lighter, more luminous centre. The Day-Date 40 was introduced in 2015 as a larger, technically updated successor to the 36mm Day-Date, and the 228xxx reference block identifies it as part of the current generation. Within Rolex's catalogue, ombré dials represent a relatively recent design departure, one that has driven strong collector interest since its debut.

Powering this reference is the Calibre 3255, Rolex's proprietary in-house movement and one of the most technically sophisticated automatic calibres in production. It features a Chronergy escapement with 15% greater energy efficiency compared to previous Swiss lever designs, a paramagnetic nickel-phosphorus escape wheel, and a 70-hour power reserve delivered by a Syloxi hairspring. The case is rated waterproof to 100 metres, the bezel is set with a continuous ring of round brilliant diamonds, and the bracelet is fabricated in matching 18ct yellow gold — either the President or Jubilee bracelet depending on configuration. Production year 2024 confirms this example is fully current-generation specification.

The 228348RBR with an ombré dial and diamond bezel is produced in lower volumes than standard dial variants, making it a genuine rarity in the secondary market. Its appeal is broad: the green ombré colour has proven enduringly popular since Rolex introduced it, aligning with broader luxury market enthusiasm for the colour. Box and papers are confirmed, which is critical for a 2024 piece — full provenance at this price point protects the buyer's investment and facilitates resale.
