Strap for Lady-Datejust 26 Rolesor Fluted Computer Diamond Jubilee

The Rolex Lady-Datejust 179173-0090 has a lug width of 13mm. This measurement is specific to the 26mm Oyster case and must be respected precisely when selecting a replacement strap to ensure a correct fit without lateral play between the lugs.

For the 179173-0090 in yellow Rolesor, the most suitable straps are polished alligator in cognac or bordeaux tones to complement the gold case, or shell cordovan in honey for those seeking a leather with tight grain and exceptional natural patina. Black vegetable-tanned calfskin offers a contemporary and versatile pairing.

To remove the original bracelet or strap, a fine-tipped springbar tool is required. The 26mm Oyster case lugs accommodate standard 1.5mm diameter spring bars. It is advisable to work with the caseback resting on a soft surface to avoid scratching the gold surfaces. If in doubt, consult a watchmaker or the Casati Milano atelier.

Yes, there are numerous aftermarket straps compatible with the 13mm lug width. milanostraps.it offers a selection of handcrafted straps made specifically for this format, featuring shaped ends and a tapered cut that replicates the geometry of the original Rolex lugs for a visually coherent result.

The lifespan of a leather strap depends on the type of leather, care, and daily use. A quality alligator or shell cordovan strap, treated with natural wax and kept away from moisture, can last between 3 and 7 years with regular wear. Casati Milano straps carry an 18-month warranty against manufacturing defects.
