Rolex Lady-Datejust 28 Yellow Rolesor — Silver Diamond Star Dial

This Lady-Datejust 28 in Yellow Rolesor presents one of the more geometrically interesting dial treatments available in the 28 mm range: a silver base set with diamond hour markers arranged in a star pattern, complemented by a diamond bezel. The absence of a model number suggests a configuration assembled or referenced under a variant designation, but the construction follows the standard Lady-Datejust 28 architecture precisely. The star diamond arrangement differentiates this from the more common individual marker layouts, creating a radial visual rhythm across the dial surface.

Calibre 2236 is the movement of record for the Lady-Datejust 28, introduced by Rolex to replace the earlier 2235 and bringing with it the Syloxi silicon hairspring — an advance that improves resistance to magnetism and temperature variation without requiring anti-magnetic shielding. The 55-hour power reserve is generous for a movement of this diameter, and COSC chronometer certification is maintained. Yellow Rolesor construction, pairing Oystersteel with 18ct yellow gold on the case accents, provides the characteristic two-tone visual warmth that has defined the Rolesor aesthetic across decades.

For collectors and buyers, the distinguishing element here is the star diamond dial configuration, which is less commonly encountered than standard diamond index or Roman numeral variants. Without a model number, provenance documentation becomes especially important — buyers should request original receipts or service paperwork to confirm the dial is factory-original rather than an aftermarket modification. Rolex's dial authentication can be confirmed through authorised service centres. The intrinsic value of the materials and movement remains substantial regardless, and Yellow Rolesor with diamond bezel holds its secondary market position reliably across cycles.
