Reference 228398TBR-0039 presents the Day-Date 40 in a 40 mm 18 kt yellow gold case built on Rolex's Oyster architecture, featuring a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown for waterproofness to 100 metres. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The green dial is rendered with Roman numeral hour markers, offering a rich interplay of color and classical typography. Beneath it runs the Calibre 3255 — a perpetual, mechanical, self-winding movement manufactured by Rolex, delivering a precision of -2/+2 seconds per day after casing and a power reserve of approximately 70 hours. The oscillator employs a paramagnetic blue Parachrom hairspring alongside high-performance Paraflex shock absorbers, and the watch holds Superlative Chronometer certification, reflecting both COSC standards and Rolex's own post-casing verification.
The President bracelet in 18 kt yellow gold, distinguished by its semi-circular three-piece links, fastens with a concealed folding Crownclasp. Functions include center hour, minute, and seconds hands alongside instantaneous day and date displays in apertures with secure rapid-setting and stop-seconds for precise time adjustment. Production year is 2024.
