The Rolex Lady-Datejust 26 Ref. 79173 represents one of Rolex’s most recognisable two-tone ladies’ configurations, combining the classic 26mm Oyster case, automatic movement and signature Rolesor aesthetic with the natural individuality of a Mother of Pearl dial.
This particular configuration is elevated by a 10-point diamond-set Mother of Pearl dial, where each natural dial displays its own variations in lustre, colour and iridescence. Paired with yellow gold accents and stainless steel, the result sits between traditional Rolex watchmaking and jewellery-led design — a configuration increasingly appreciated by collectors seeking discontinued smaller-case Datejust references with precious-material dials.
 
WLCSG CURATOR NOTE:
Within the Lady-Datejust family, dial configuration makes a significant difference. Standard champagne and silver dials are widely recognised, while Mother of Pearl examples offer natural variation — no two pieces display precisely the same play of colour, pattern and lustre.
The combination of MOP + 10 diamond markers + two-tone Jubilee styling gives this Ref. 79173 considerably more jewellery presence than a conventional Datejust 26, while retaining the practicality of Rolex automatic watchmaking.
For collectors drawn to smaller, jewellery-forward Rolex watches, this is the kind of discontinued configuration we find particularly compelling: recognisably Rolex from across the room, but distinctive enough in its dial and detailing to reward a closer look.
