Rolex Datejust 36 36 mm 126234BKSO Steel/White Gold Black Rolex Datejust 36 36 mm 126234BKSO Steel/White…

The Rolex Datejust is one of the most enduring icons in watchmaking, having introduced the automatic date display at 3 o'clock when it debuted in 1945 — a first in the history of wristwatches. Across more than seven decades of continuous production, the Datejust has evolved in material, dial, and bracelet options while retaining its unmistakable silhouette. The 36mm case diameter remains the purest expression of the original proportions, making reference 126234BKSO a direct heir to that storied lineage.

The 126234BKSO is built on Rolex's Oyster case, measuring a versatile 36mm in diameter and constructed from a combination of Oystersteel — Rolex's proprietary corrosion-resistant steel — and 18k white gold. The white gold is used for the fluted bezel, whose precisely machined grooves catch and scatter light with an effect that is immediately recognizable and deeply associated with the Datejust's heritage. The result is a watch that reads as both sporty and refined depending on context.

At the heart of the dial is a clean black surface that provides exceptional contrast with the white gold indices and hands, ensuring effortless legibility at a glance. The black dial on this reference gives the watch a contemporary, bold character while still honoring the classical layout that has defined the Datejust for generations. Whether worn against a shirt cuff or a casual sleeve, the dial commands attention without ostentation.

Powering the watch is Rolex's self-winding automatic movement, delivered here in brand-new condition. The Datejust 36 platform is engineered to Rolex's exacting standards of precision, reliability, and chronometric performance, ensuring the movement performs consistently for daily wear. The Oyster bracelet — itself a benchmark of integrated bracelet design — adds comfort and durability, locking the whole package together as a cohesive tool-watch aesthetic dressed in premium materials.

With 100 meters (330 feet) of water resistance, the Datejust 36 ref. 126234BKSO is entirely at home in daily life, whether at the office, a formal dinner, or a weekend outing. The 36mm case size occupies a sweet spot that wears equally well on a range of wrist sizes, making this reference one of the most universally flattering in the Rolex catalog.
