Reference 228238-0042 houses the timepiece in a 40 mm 18 kt yellow gold Oyster case featuring a fluted bezel, solid case back, and a screw-down winding crown with Twinlock double waterproofness. Scratch-resistant sapphire crystal with a Cyclops lens over the date protects the white dial, which displays the day and date through apertures alongside Roman numeral hour markers. Water resistance reaches 100 metres / 330 feet.
Power comes from the Calibre 3255 perpetual, mechanical, self-winding movement — a Manufacture Rolex calibre certified as a Superlative Chronometer to a precision of -2/+2 seconds per day after casing. The movement features a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and an approximately 70-hour power reserve. Functions include centre hour, minute, and seconds hands with instantaneous day and date setting and stop-seconds for precise time adjustment.
The watch is presented on an 18 kt yellow gold President bracelet with semi-circular three-piece links secured by a concealed folding Crownclasp. This example comes as a complete set, including the Rolex box and Rolex card.
