The Lady-Datejust 279135RBR-0027, seen from the bench

The Lady-Datejust 279135RBR-0027 is a 28mm Everose gold women's watch from the 2018 generation, powered by the Rolex Caliber 2236 (COSC-certified chronometer with silicon balance and approximately 55-hour power reserve). It features a fluted bezel set with brilliant-cut rubies, a mother-of-pearl dial adorned with diamonds, and a Jubilee bracelet in Everose gold with Crownclasp closure. The 14mm lug width is a non-standard specification requiring precision-made or hand-fitted straps with a profile of 2.5–3.5mm thickness to maintain the case's refined proportions.

Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279135RBR-0027?

The Rolex Lady-Datejust 279135RBR-0027 features a 28mm case with a lug width of 14mm. This measurement falls outside the most common aftermarket standard sizes and therefore requires a strap that has been specifically made or hand-trimmed to this width. It is advisable to verify the measurement with a digital calliper prior to purchase.

What is the best strap for the Rolex Lady-Datejust 279135RBR-0027?

For the Lady-Datejust 279135RBR-0027 in Everose gold, a vegetable-tanned alligator strap is the most coherent choice given the jewellery-oriented nature of the piece. Cognac or bordeaux tones complement the warm hues of the rose gold and harmonise with the ruby-set bezel. Shell cordovan is a refined alternative for those who prefer a smooth, lustrous surface. The buckle or deployant clasp should be in rose gold to ensure metallic continuity.

How do you change the strap on a Rolex Lady-Datejust 279135RBR-0027?

The bracelet or strap on the Lady-Datejust 279135RBR-0027 is removed via the spring bars located at the case lugs. A suitable push-pin or screw-type spring bar tool of the correct diameter must be used to avoid scratching the Everose gold lugs. The operation should be carried out on a soft surface, and in case of any doubt, it is recommended to seek assistance from a watchmaker or the Casati Milano atelier for professional fitting.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279135RBR-0027?

Yes, aftermarket straps compatible with the 14mm lug width of the Lady-Datejust 279135RBR-0027 do exist. It is essential to select manufacturers who work specifically with this non-standard size, guaranteeing millimetre-precise ends and an appropriate strap thickness (between 2.5 and 3.5mm) to respect the proportions of the 28mm case. Milanostraps.it offers a selection of 14mm straps handcrafted in Italy.

How long does a leather strap last on a Rolex Lady-Datejust 279135RBR-0027?

The lifespan of a leather strap depends on the quality of the hide, frequency of wear, and exposure to moisture and perspiration. A high-quality alligator or shell cordovan strap, with proper care, can last between three and five years whilst developing an attractive patina. Premium calf leather has an average lifespan of two to three years. The Casati Milano guarantee covers manufacturing defects for 18 months. Prolonged contact with water should be avoided, and a dedicated leather conditioner should be applied periodically.
