Rolex Day-Date President 118239

The Reference 118239 denotes the 36mm Day-Date from the 118xxx generation (c. 2000-2019), specified with a case and President bracelet in 18k white gold (9) and a fluted bezel (3). As the successor to the 18239, this reference introduced significant structural and mechanical upgrades. It is built on a heavier case chassis with thicker, fully polished lugs and is fitted with a solid-link President bracelet (Ref. 83209) that eliminates the stretch common in older hollow-link versions. The watch operates on the Caliber 3155 movement, a 31-jewel automatic chronometer notable for its double quickset day-date complication. Later production models of this reference incorporate Rolex’s patented blue Parachrom hairspring, enhancing its anti-magnetic and shock-resistant properties.
