Rolex, Day-Date 36, 128235, Eisenkiesel Dial, Rose Gold, Presidential Bracelet, 36mm

The watch is built with a 36mm Oyster case crafted from 18ct rose gold, giving the overall structure a warmer tone that contrasts with the more mineral-like texture of the dial.

Its Oyster architecture combines a screw-down caseback with a Twinlock winding crown, forming a sealed construction engineered for water resistance up to 100 meters.

The fluted bezel frames the case with sharply machined ridges that generate narrow reflections around the perimeter, creating a more defined outer edge surrounding the dial.

At the center is an Eisenkiesel dial, cut from natural stone with iron oxide and quartz inclusions, giving the surface an irregular composition that cannot be reproduced identically.

Unlike lacquer or sunray dials, the texture and tonal variation come directly from the mineral structure itself rather than from applied finishing techniques.

The dial displays shifting shades of brown, gray, and copper depending on the angle of light, with naturally occurring veining and granular patterns distributed unpredictably across the surface.

Applied rose gold hour markers maintain readability while allowing the stone dial itself to remain the dominant visual element of the watch.

The day aperture spans across 12 o’clock, while the date display at 3 o’clock is magnified through the Cyclops lens, ensuring both indications remain clear against the textured background.

Its President bracelet is crafted in matching rose gold, featuring semi-circular three-piece links engineered to contour naturally around the wrist while balancing the watch's weight evenly.

A concealed Crownclasp integrates directly into the bracelet, preserving a continuous metallic surface without visible interruption when secured.

Inside, the watch features the Rolex caliber 3255 automatic movement, featuring a Chronergy escapement and an optimized energy transfer system for improved efficiency and long-term precision.

The movement delivers approximately 70 hours of power reserve and operates within Rolex’s Superlative Chronometer tolerance of -2/+2 seconds per day after casing.

Because the Eisenkiesel dial is formed from natural stone rather than a manufactured surface, the watch's visual identity is shaped more by organic variation and mineral texture than by uniform color or finish.
