Rolex Datejust 36 Yellow Rolesor — Silver Diamond Dial, Diamond Bezel | Ref. 116243

Reference 116243 belongs to the previous generation of the Datejust 36 — the generation defined by the calibre 3135 and the 116xxx reference series that ran from the mid-2000s through to the late 2010s introduction of the 126xxx series. This particular example presents in Yellow Rolesor with a 52 brilliant-cut diamond bezel and a silver dial set with diamond hour indices — a jewellery-forward configuration that was a consistent top-seller throughout the reference's production run. Yellow Rolesor combines an Oystersteel case with 18 ct yellow gold bezel, crown, and Jubilee bracelet centre links.

Calibre 3135 is the movement, one of the most respected ébauches in Swiss horology. Produced by Rolex from 1988 onward, it features a Glucydur balance wheel, a Breguet overcoil hairspring, and a bidirectional rotor with the perpetual winding system. Power reserve is approximately 48 hours. While the 3135 lacks the 70-hour reserve and Chronergy escapement of its successor, it is extraordinarily well-proven over decades of continuous production and is regarded as among the most reliable and serviceable automatic movements ever made.

For collectors, the 116243 with diamond bezel and dial represents a cost-effective entry into the gem-set Datejust segment: older-generation references typically trade at meaningful discounts to their current 126xxx equivalents despite offering nearly identical practical functionality. An excellent choice for buyers who prioritise diamond coverage and the classic Jubilee bracelet presentation over having the latest calibre.
