Lady-Datejust 279173-0018— lug 14mm

The Rolex Lady-Datejust 279173-0018 features a 28mm Oyster case with a lug width of 14mm. This measurement is specific to the entire Lady-Datejust 28mm line and must be respected precisely when selecting a replacement strap to ensure correct fitment and visual coherence.

For the Lady-Datejust 279173-0018 in 18ct yellow gold, a polished or semi-matte alligator strap is the most coherent choice for the formal character of the piece. Shell cordovan is a premium alternative for those who prefer a denser, more structured leather. For casual contexts, vegetable-tanned calf leather offers excellent hand feel and develops a beautiful patina over time. A deployant clasp is recommended for daily wear.

Replacing the strap on the Lady-Datejust 279173-0018 requires a spring bar tool to remove the spring bars located between the 14mm lugs. It is advisable to work on a soft surface to prevent scratches to the yellow gold case. For a precise, risk-free replacement, entrusting the work to a specialist or bespoke atelier is strongly recommended.

Yes, high-quality aftermarket straps are available for the Lady-Datejust 279173-0018, provided they feature a precisely calibrated 14mm attachment. Milano Straps produces bespoke straps for this reference in various materials — alligator, calf leather, shell cordovan — with steel or gold buckles and deployant clasps chosen to complement the 18ct yellow gold case.

The lifespan of a leather strap depends on the material, craftsmanship, and wearing habits. A quality alligator strap, worn with care and rotated with other straps, can last between three and five years whilst retaining good structural integrity. Shell cordovan generally offers superior longevity due to the density of its fibres. Prolonged exposure to perspiration and water significantly reduces durability; a deployant clasp helps preserve the strap's geometry over time.
