Strap for Lady-Datejust 28 Yellow Gold Diamond / President / Champagne Diamonds

The Rolex Lady-Datejust 279138rbr-0006 features a 28 mm case with lugs tapering to a width of 14 mm at the strap attachment point. This measurement must be taken internally between the two lugs using a millimetre calliper, and is essential for selecting a correctly fitting replacement strap.

For the yellow gold variant of the 279138rbr-0006, the most suitable materials are alligator leather with mississippiensis or hornback grain, shell cordovan, and vegetable-tanned calf leather. Shades such as burgundy, midnight blue, cognac, or black pair most effectively with the 18-carat yellow gold case. The buckle or deployant clasp should ideally be finished in gold PVD or yellow gold for visual consistency.

Removing the original bracelet or strap from the Lady-Datejust requires a springbar tool — a forked instrument used to compress the 14 mm spring bars housed within the lugs. Care must be taken not to scratch the 18-carat yellow gold case. For a first-time strap change, it is advisable to consult a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 14 mm lug width is technically compatible with the 28 mm Rolex Lady-Datejust, including the 279138rbr-0006. Milano Straps offers a curated selection of handcrafted 14 mm straps in leather, rubber, and technical materials, with buckles and deployant clasps available in various metal finishes.

The lifespan of a leather strap depends on the type of hide, maintenance, and frequency of use. A quality alligator or shell cordovan strap, cared for properly and kept away from prolonged contact with water and perspiration, can last between three and seven years whilst retaining a refined appearance. Vegetable-tanned calf straps develop a distinctive patina over time. Milano Straps provides an 18-month guarantee against manufacturing defects.
