Housed in a 40 mm 18 kt yellow gold Oyster case with a monobloc middle, screw-down case back, and screw-down Twinlock winding crown, reference 228398TBR-0033 offers waterproofness to 100 metres / 330 feet. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the dial clearly legible.
The white dial carries Roman numeral hour markers and displays the full day and date in dedicated apertures via instantaneous, secure rapid-setting. Power comes from the Calibre 3255, a perpetual mechanical self-winding movement manufactured by Rolex, featuring a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, a precision of -2/+2 seconds per day after casing, and a power reserve of approximately 70 hours. It carries Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
The watch is completed by an 18 kt yellow gold President bracelet with semi-circular three-piece links, secured by a concealed folding Crownclasp. Production year is 2024.
