Rolex Datejust 36 Yellow Rolesor — Black Index Dial with Diamond Bezel | Ref. 116243

Reference 116243 is a Datejust 36 in Yellow Rolesor, distinguished by the addition of a factory diamond-set bezel that transforms the already characterful two-tone configuration into something more overtly dressy. The cut diamond bezel replaces the standard fluted or smooth option with a continuous band of channel-set brilliant diamonds, amplifying the visual impact of the yellow gold accents that run through the Rolesor construction. The black index dial provides a strong contrast anchor, allowing the diamond elements to read clearly without the composition becoming overwhelming. This reference bridges the classic Datejust heritage — in continuous production since 1945 — with an elevated jewellery dimension.

The 116243 houses the Calibre 3135, a movement that underpinned the Datejust 36 for decades before the transition to the 3235 with the 126xxx generation. The 3135 runs at 28,800 vph with a 48-hour power reserve and earned widespread respect among watchmakers and collectors alike for its exceptional reliability and serviceability. The Parachrom hairspring provides enhanced resistance to shocks and magnetic fields. Within the 36mm Oyster case in Yellow Rolesor, the bi-directional Perpetual rotor winds the mainspring through normal wrist movement. The combination of Jubilee bracelet with Rolesor construction creates a cohesive, layered aesthetic throughout.

On the collector market, diamond bezel Datejust references from the 116xxx generation occupy an interesting position — genuinely rare compared to non-diamond variants but priced accessibly relative to newer 126xxx models. Buyers who prefer the 36mm case size and the 3135 movement's proven track record find this generation appealing for its balance of horological substance and decorative ambition. The black dial with diamond bezel combination is among the most requested configurations in the pre-owned market, ensuring healthy liquidity.
