Lady-Datejust 279178-0014— lug 14mm

The Rolex Lady-Datejust reference 279178-0014 has a lug width of 14mm. This is a dimension specific to Rolex ladies' models with a 28mm case and requires dedicated straps, not interchangeable with the standard 18mm or 20mm sizes used on men's models.

For an 18-carat yellow gold case, alligator straps in cognac, honey or bordeaux tones offer the greatest aesthetic coherence. Shell cordovan and vegetable-tanned calf leather are high-quality alternatives that develop a personal patina over time. For more active settings, vulcanised rubber maintains a sportive legibility without compromising the character of the watch.

Strap replacement requires a fine-tip spring bar tool with a 0.8mm head. The spring bars on the Lady-Datejust are integrated within the case lugs: the lateral pins must be compressed with precision to avoid scratching the gold surfaces. If you lack experience, it is advisable to entrust the operation to a watchmaker or to the Casati Milano atelier.

Yes. Aftermarket straps with a 14mm lug width are compatible with reference 279178-0014, provided they respect the dimensional tolerance of ±0.2mm and that the spring bars have the correct diameter (typically 1.5mm). Milanostraps.it offers a selection of handcrafted 14mm straps already shaped for this specific model.

A quality leather strap — alligator, shell cordovan or vegetable-tanned calf — typically lasts between 2 and 4 years with daily wear, depending on exposure to perspiration, water and UV rays. Regular conditioning with a dedicated leather cream and rotation between multiple straps significantly extends the lifespan of the piece. Casati Milano straps carry an 18-month warranty against manufacturing defects.
