FAQ

What is the lug width of the Rolex Lady-Datejust 279178-0001?

The Rolex Lady-Datejust 279178-0001 has a lug width of 14mm. This measurement should always be verified with a digital calliper directly between the lugs before purchasing a replacement strap, as even a one-millimetre discrepancy will prevent correct fitting.

What is the best strap for the Rolex Lady-Datejust 279178-0001?

For an 18ct yellow gold case measuring 28mm, an alligator strap with vegetable tanning is the most coherent choice with the reference's pedigree. Shell cordovan offers a denser, more compact alternative with exceptional longevity. Both options are available in 14mm lug width — bespoke via Casati Milano atelier or ready-made through the milanostraps.it online catalogue.

How do you change the strap on a Rolex Lady-Datejust 279178-0001?

Strap replacement requires a spring bar tool to compress the spring bar ends housed within the 14mm lugs. Work on a soft surface to protect the yellow gold case from scratches. If in doubt, entrust the operation to a watchmaker or to the Casati Milano atelier, who can perform the swap as part of the bespoke fitting service.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279178-0001?

Yes. Any strap featuring a 14mm attachment width with standard spring bars is technically compatible with the Rolex Lady-Datejust 279178-0001. milanostraps.it offers a curated selection of handcrafted straps in multiple materials specifically produced for 14mm lug widths, with finishing quality befitting a yellow gold timepiece.

How long does a leather strap last on a Rolex Lady-Datejust 279178-0001?

Longevity depends on material and frequency of wear. A quality vegetable-tanned alligator strap, rotated regularly and kept away from moisture and perspiration, can last between three and five years while retaining structural integrity and aesthetic appeal. Shell cordovan, owing to its fibre density, typically outlasts conventional leathers. All Casati Milano bespoke straps carry an 18-month warranty against manufacturing defects.
