Strap for Rolex Pearlmaster 81315

The lug width (ansa) of the Rolex Pearlmaster 81315 is 17 mm. This measurement is taken internally, edge to edge, between the two metal collars where the spring bars are inserted. It is a dimension specifically engineered by Rolex to suit the proportions of the female wrist.

Alligator leather in vegetable tanning is the classical choice: its characteristic grain and golden patina that develops over time harmonise visually with the Everose gold case. Shell cordovan offers inherent lustre and superior resistance to wear. For a contemporary aesthetic, oiled calf leather or FKM rubber are refined options that preserve elegance.

Changing the strap requires a dedicated tool (spring bar remover). Insert the small end of the tool under the metal spring bar from the side of the old strap, lift gently until the bar disengages from its seat, then withdraw the strap. Repeat on the opposite side. Proceed with care to avoid scratching the gold case.

Yes, provided the lug width is precisely 17 mm and the leather thickness does not exceed approximately 10 mm. A quality artisanal strap guarantees both geometric and visual compatibility with the Everose case. Rely on craftsmen who measure your specific watch's lug width with precision.

Durability depends on daily wear and leather quality. Vegetable-tanned alligator or shell cordovan last 3–5 years with moderate use. Oiled calf leather lasts 2–4 years. FKM rubber may reach 5–7 years. Frequency of wear and perspiration influence longevity. Regular maintenance (gentle cleaning, dry storage) significantly extends strap life.
