Lady-Datejust 279178-0004— lug 14mm

The Rolex Lady-Datejust 279178-0004 has a lug width of 14mm. This dimension is determined by the proportions of the 28mm 18-carat yellow gold case and should be verified with a digital calliper before purchasing an aftermarket strap.

For an 18-carat yellow gold case measuring 28mm, a vegetable-tanned alligator strap is the most aesthetically and qualitatively coherent choice. Recommended colours include cognac, bordeaux, forest green or fine-grain black. A yellow gold deployant clasp completes the pairing with consistent metallic continuity.

To remove the original or aftermarket strap from the Lady-Datejust 279178-0004, a dedicated spring bar tool is required. The spring bars are compressed laterally within the lug to release them. It is advisable to work on a soft surface to avoid scratching the yellow gold case. Alternatively, any watchmaker or the Casati Milano service can perform this operation in a matter of minutes.

Yes. Aftermarket straps compatible with the Lady-Datejust 279178-0004 must have a lug width of 14mm. Milanostraps.it offers a selection of handcrafted straps in alligator, calf leather and shell cordovan, made to measure for this specific geometry, with spring bars included and an 18-month warranty on workmanship.

The lifespan of a leather strap depends on the material, the tanning process and daily care. A quality vegetable-tanned alligator strap, with regular but not intensive wear, maintains its structural and aesthetic integrity for 3 to 5 years. Shell cordovan, owing to the density of its fibres, is among the most durable options. Prolonged exposure to perspiration, fragrances and water accelerates deterioration: it is advisable to rotate between two straps and treat the leather periodically with appropriate conditioners.
