What is the best strap for the Rolex Lady-Datejust 279135RBR-0025 in Everose gold?

For the Lady-Datejust 279135RBR-0025 in Everose gold, a vegetable-tanned alligator strap in bordeaux, cognac, or bottle green best complements the warm chromatic tone of rose gold. Polished smooth calfskin is a strong formal alternative. For more active contexts, high-grade vulcanised rubber or a silk NATO strap are appropriate choices, fully compatible with the 100-metre Oyster water resistance.

How do you change the strap on a Rolex Lady-Datejust 279135RBR-0025?

Strap replacement on the Lady-Datejust 279135RBR-0025 is carried out using standard 14mm spring bars. A forked spring bar tool is recommended to avoid scratching the Everose gold lugs.
