The case is crafted from polished stainless steel and topped with a polished 18kt Everose gold fluted bezel. The screwed-down Twinlock crown, also in polished 18kt Everose gold, provides two sealed zones — one within the crown tube and one inside the crown itself. The slate dial is dressed with applied polished Everose gold index hour markers and matching hour and minute hands, both carrying luminous fill, while a fine minutes/seconds track runs along the dial perimeter. A date window at 3 o'clock is framed by a Cyclops magnifying lens.
Inside beats the Rolex in-house caliber 3235, oscillating at 28,800 vph with 31 jewels and an approximately 70-hour power reserve. The movement incorporates a paramagnetic blue Parachrom hairspring, a Chronergy escapement, and high-performance Paraflex shock absorbers. The watch holds Superlative Chronometer certification, meaning the movement is COSC certified before casing and then tested a second time by Rolex after final assembly.
Completing the watch is an 18kt Everose gold and stainless steel Jubilee bracelet, echoing the two-tone character of the case and bezel. Reference 126231-0013 is listed as a unisex piece suited to a broad range of wearers and occasions.
