Housed in a 40 mm Oyster case crafted from 18 kt Everose gold, the Day-Date 40 ref. 228345RBR-0024 features a bezel set with diamonds and a screw-down winding crown equipped with the Twinlock double waterproofness system. The Oyster architecture employs a monobloc middle case and screw-down case back, delivering water resistance to 100 metres / 330 feet, while scratch-resistant sapphire crystal with a Cyclops lens over the date ensures lasting clarity.
The chocolate dial is fitted with a Chromalight display offering long-lasting blue luminescence for legibility in low light. At the wrist, the President bracelet — constructed with semi-circular three-piece links in 18 kt Everose gold — secures via a concealed folding Crownclasp, lending the piece its characteristic refined presence.
Inside beats the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex, achieving a precision of -2/+2 seconds per day after casing and carrying Superlative Chronometer certification. The oscillator incorporates a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, with bidirectional winding via a Perpetual rotor and a power reserve of approximately 70 hours. Day and date are displayed instantaneously in apertures with secure rapid-setting. Production year: 2023.
