The Lady-Datejust 279178-0010, seen from the bench

The Rolex Lady-Datejust 279178-0010 is an iconic feminine timepiece featuring a 28mm case in 18-carat yellow gold with fluted bezel and champagne dial. Introduced in 1957, this model houses the Rolex caliber 2236, a movement developed specifically for women's watches and certified by COSC. The 2236 incorporates the Syloxi hairspring-balance system in silicon for magnetic stability, offers a 55-hour power reserve, and delivers water resistance to 100 meters. The lug width is 14mm, a precise specification essential for correct strap selection.

Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279178-0010?

The Rolex Lady-Datejust 279178-0010 has a lug width of 14mm. This measurement should be taken with a digital calliper inside the lugs, between the two lug walls, at the narrowest point. It is a specific dimension of this 28mm case and is not interchangeable with 13mm or 15mm straps without modification.

What is the best strap for the Rolex Lady-Datejust 279178-0010?

For an 18-carat yellow gold case, square-scale alligator leather is the most aesthetically coherent choice: its three-dimensional grain texture complements the warm reflections of the gold, developing a refined patina over time. Shell cordovan is an equally distinguished alternative for those who prefer a denser, more compact surface. In both cases, a yellow gold buckle or deployant clasp completes the visual harmony.

How do you change the strap on a Rolex Lady-Datejust 279178-0010?

Removing the original strap requires a spring bar tool appropriate for the 14mm lug width. Insert the tool into the lug notch, compress the spring bar mechanism, and slide the strap free. While this can be done independently with the correct tools, on a yellow gold case it is advisable to entrust the operation to a watchmaker or specialist atelier to avoid scratching the polished surfaces.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279178-0010?

Yes. Aftermarket straps with a 14mm attachment are compatible with the Lady-Datejust 279178-0010, provided the spring bar diameter is correct and the strap length is suited to a female wrist (typically 105/65mm or made to measure). Milano Straps offers a selection of handcrafted 14mm straps in alligator, calf leather, and shell cordovan, with precious metal buckles available on request.

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

The lifespan of a leather strap depends on the type of leather, frequency of use, and maintenance. A high-quality vegetable-tanned alligator strap, worn with care and kept away from prolonged contact with water and perspiration, will retain its structural and aesthetic integrity for 3 to 5 years. Shell cordovan, owing to its dense fibre structure, tends to last considerably longer. Regular conditioning with a suitable leather cream will significantly extend the strap's service life.
