BUILD — Two-Tone 904L Stainless Steel Case Design
The 36 mm case of the Rolex Datejust 126231 is constructed using a combination of both 904L stainless steel and rose gold-plated 904L stainless steel to produce a two-tone design. The polished sides of the case deliver a reflective surface finish, whereas the precisely designed lugs create a seamless connection between the case and bracelet.
Rose gold-plated winding crown complements the fluted bezel and bracelet middle links. The slender case silhouette together with curved lugs and well-defined edges creates an architectural look for the watch.
DIAL — Slate Roman Display with Diamond-Set VI and IX
Dial color: Slate
Hour markers: Applied Roman numeral markers
Diamond markers: Diamond-set VI at 6 o’clock and IX at 9 o’clock
Date display: Calendar window positioned at 3 o’clock
Date magnifier: Cyclops lens mounted above the date aperture
Hour and minute hands: Straight baton-shaped design
Seconds hand: Long, slender central seconds hand
Crystal: Scratch-resistant sapphire crystal
The slate dial uses a subtle metallic finish as the background for raised Roman numerals. The VI and IX markers are set with decorative stones, providing a brighter visual contrast at the lower and left sections of the dial.
Date aperture in frame form can be found at the 3 o’clock position under the Cyclops magnifying glass. The straight hour and minute hands are accompanied by the seconds hand in the center, while the minute scale around makes for an outer boundary.

BEZEL — Rose-Gold-Plated Fluted Design
This type of bezel is constructed using the classic fluted triangular design that is coated in rose-gold plating. The fluted pattern is composed of sharp ridges that outline the sapphire crystal as well as provide a contrast between the dial and the polished stainless-steel case.
The fluted bezel reflects light from various angles to highlight the warmth of the rose-gold finish while keeping its shape symmetric throughout the bezel’s entire circumference.
BRACELET — Two-Tone Five-Piece Link Design
Outer links: brushed 904L stainless steel
Inner links: polished rose-gold plated 904L stainless steel
Structure: Five-piece link arrangement
Clasp: Folding stainless-steel clasp
Clasp detail: Raised crown emblem
Conclusion: Brushed and Polished
This is a combination of silver-toned outer links and rose gold-toned center links. The bracelet features a five-link mechanism with small-sized links to make it more flexible and intricate.
The folding clasp follows the same alternating metal treatment and incorporates a raised crown emblem on its center section. The underside includes engraved stainless-steel markings and reference details.
Automatic Movement Details
The Rolex Datejust 126231 is powered by a Dandong 3235 automatic mechanical movement. It supports central hour, minute and seconds functions together with the calendar display at 3 o’clock.
The automatic winding system generates operating energy through rotor movement. The crown is used for manual winding, time adjustment and calendar setting, allowing the primary functions to be controlled through a single operating point.
