The venerable Day-Date has long stood as a paragon of Rolex ingenuity. Traditionally cased at 36mm, a larger 41mm variant debuted in 2008 as the Day-Date II. Today, the Day-Date family is available in classic 36mm and contemporary 40mm options.

While Rolex has always pioneered material innovations, like hardstone dials, recent collector enthusiasm for such uniqueness has grown exponentially. To date, the maison has incorporated 25 exquisite hardstones, each prized for rarity and peerless craftsmanship.

In 2021, Rolex subtly unveiled its newest creation – the 25th hardstone dial, Eisenkiesel. This Germanic semi-precious quartz, speckled with iron inclusions, normally manifests in warm yellow, red or brown hues. Its hardy 7 Mohs hardness provides durable elegance. Here, set against Rolex's own Everose gold case, the dial dazzles in its unique pattern of brown hues, further embellished with diamond-set Roman numeral indexes in a dazzling display of jewelry watchmaking.

Offered here in nearly unworn condition complete with accompanying accessories, this 36mm Rolex Day-Date ref. 128235 represents an opportunity to acquire the extraordinary Eisenkiesel dial at auction, bypassing the boutique waiting list. For collectors of exceptional Day-Dates, the present example is a sublime horological treasure.
