Lady-Datejust 279161-0020— lug 14mm

The Rolex Lady-Datejust 279161-0020 features a 28mm case with a lug width of 14mm. This measurement is taken with a calliper positioned between the inner faces of the two lugs, at the point of contact between lug and strap. It is a specific dimension requiring straps manufactured to this exact nominal size.

For the Lady-Datejust 279161-0020 in Everose and Oystersteel, the most suitable materials are vegetable-tanned alligator with bombé grain (the canonical pairing for Rolex bi-material cases), smooth box calf for a minimalist register, and shell cordovan for those seeking character and developing patina over time. Chromatically, cognac, tobacco and bordeaux tones complement the Everose gold and champagne dial most effectively.

To replace the strap on the Lady-Datejust 279161-0020, a fine-tipped spring bar tool or dedicated spring bar screwdriver is required. Insert the tool into the lug notch, compress the spring bar and slide the strap out laterally. Care should be taken to avoid scratching the Everose lugs. If in doubt, it is advisable to consult a watchmaker or the Casati Milano atelier.

Yes. Aftermarket straps compatible with the Lady-Datejust 279161-0020 must have a lug width of 14mm and standard spring bars with a diameter of 1.5mm. Milano Straps offers a selection of handcrafted 14mm straps on milanostraps.it, with a millimetre-precise fitting to ensure correct retention on the lugs of the Lady-Datejust 28mm case.

The longevity of a leather strap depends on the quality of the hide, the tanning process and daily use. A premium vegetable-tanned alligator strap, used with care and kept away from excessive perspiration and moisture, maintains structural and aesthetic integrity for 3 to 5 years. With a deployant clasp rather than a traditional buckle, lifespan increases considerably as mechanical stress on the leather is significantly reduced. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
