Rolex Day-Date 40 Yellow Gold - Fluted / Black Ref. 228238-0067

The Rolex Day-Date 40 debuted in 2015 and marked a dimensional recalibration of the collection, positioned between the classic Day-Date 36 and the earlier Day-Date II. The case measures 40 mm in diameter and is crafted from 18 ct yellow gold, using Rolex’s monobloc Oyster architecture with a screw-down case back and winding crown. Water resistance is rated to 100 metres. Reference 228238-0067 was added to the collection in 2023. It features a fluted bezel in yellow gold framing a scratch-resistant sapphire crystal with a Cyclops lens above the date aperture. The dial is executed in Black, with applied hour markers and hands filled with Chromalight luminescent material. The day of the week is displayed in full through an aperture at 12 o’clock, with the date shown at 3 o’clock. Powering the Day-Date 40 is the Rolex calibre 3255, a self-winding mechanical movement operating at 28,800 vibrations per hour. The movement incorporates a blue Parachrom hairspring, Paraflex shock absorbers, and a bidirectional Perpetual rotor. It delivers an approximate power reserve of 70 hours and supports instantaneous day and date displays with secure rapid setting, as well as stop-seconds for precise time adjustment. Following casing, the movement is certified as a Superlative Chronometer. The watch is fitted with the President bracelet, composed of semi-circular three-piece links in 18 ct yellow gold. It is secured by a concealed folding Crownclasp and integrates seamlessly with the case.
