The Rolex Day-Date 36 reference 128235-0041 is a prestigious luxury timepiece crafted from 18k Everose gold, a proprietary pink gold alloy developed by Rolex to maintain its luster over time. This model features a 36mm Oyster case equipped with a fluted bezel and a screw-down Twinlock winding crown, ensuring water resistance up to 100 meters. The defining characteristic of this reference is its unique dial made from eisenkiesel, a dark brown, delicately veined ferruginous quartz. Because it is a natural stone, each dial possesses a distinct pattern, providing a unique personality to every watch. The face is further elevated by 18k gold hour markers set with 32 diamonds, along with diamond-set Roman VI and IX numerals.
At its core, the watch is powered by the in-house caliber 3255, a self-winding mechanical movement that offers a power reserve of approximately 70 hours and a precision of -2/+2 seconds per day. The movement supports the collection’s signature complications: a central time display, an instantaneous date window at 3 o’clock magnified by a Cyclops lens, and the day of the week spelled out in full at the 12 o’clock position. The timepiece is paired with the iconic President bracelet, featuring semi-circular three-piece links and a concealed folding Crownclasp, which is reserved exclusively for the Day-Date and certain Datejust models in precious metals.
General reviews of this specific Day-Date 36 often emphasize the striking aesthetic of the eisenkiesel dial, noting that the rich black-brown tones and reddish veining create a warm, sophisticated look that complements the Everose gold construction. Collectors appreciate the rarity of hardstone dials in the modern Rolex catalog and the exclusivity associated with the unique nature of the stone. While some find the 36mm diameter more traditional and versatile for various wrist sizes, others highlight that the weight of the solid gold and the brilliance of the diamond settings make it a significant statement piece. The caliber 3255 is highly regarded for its reliability and magnetic resistance, though most enthusiasts view this particular reference primarily as a pinnacle of luxury design rather than a strictly utilitarian instrument.
