Reference 18238 represents the five-digit era of the Day-Date, pairing a 36mm 18K yellow gold case with a fluted yellow gold bezel and scratch-resistant sapphire crystal fitted with a Cyclops lens over the date. The champagne dial carries factory Rolex diamond hour markers, and the day display appears at 12 o'clock while the date at 3 o'clock reads clearly through the magnifying lens. Water resistance is rated to 100 meters.
The President bracelet in 18K yellow gold secures with a concealed folding Crownclasp, and the screw-down Twinlock crown seals the case. Power comes from the self-winding Caliber 3155, which provides instantaneous day and date changes, an approximately 48-hour power reserve, and carries Superlative Chronometer (COSC) certification for accuracy.
This example is offered in mint condition and comes with a store warranty and a Rolex box, making it a well-documented piece for anyone drawn to solid-gold Rolex collecting.
