Rolex Datejust Yellow Rolesor — Silver Index Dial | Ref. 279163

Reference 279163 presents the Lady-Datejust 28 in Yellow Rolesor — Rolex's proprietary combination of Oystersteel and 18 ct yellow gold — delivering a two-tone aesthetic that has defined aspirational watch design for decades. The Silver Index dial provides a clean, luminous backdrop against which applied gold hour markers and hands stand in crisp relief. At 28 mm, the Oyster case wears with understated elegance, complemented by the characteristic fluted or smooth bezel options that define this reference within the broader Datejust family.

Beneath the Oyster case, Calibre 2236 provides the mechanical foundation. This manufacture movement, developed by Rolex to meet the dimensional constraints of the Lady-Datejust, features the Syloxi hairspring — a silicon-based component that eliminates the need for a traditional overcoil and renders the regulator immune to magnetic interference. Combined with the Parachrom hairspring technology informing its design lineage, the 2236 achieves COSC chronometer certification standards and delivers approximately 55 hours of power reserve.

Reference 279163 holds broad collector appeal as a Rolesor configuration — a format that has been part of the Datejust DNA since Hans Wilsdorf introduced the two-tone concept in the mid-twentieth century. The yellow gold and steel pairing remains one of the most versatile in watchmaking, equally suited to formal and casual contexts. For buyers seeking an entry into the gold Rolex universe without the weight or cost of a fully precious-metal case, the 279163 in Yellow Rolesor represents a particularly well-considered choice.
