Strap for Rolex Pearlmaster 81159

The Rolex Pearlmaster 81159 features a lug width of 17 millimetres. This dimension is specific to the model and corresponds to the proportions of the 34mm case. To verify that a strap is compatible, ensure it is manufactured with 17mm lugs, which can be measured by inserting a ruler between the internal attachment points of the case.

For the Pearlmaster 81159, we recommend alligator in black or brown for absolute elegance, or calf leather with vegetable tanning for warmth and natural patina development. Black alligator creates a refined contrast with the white gold and diamonds, whilst aged calf develops personal character over time. Avoid decorative straps: this model thrives on chromatic essentiality.

The Pearlmaster 81159 uses a deployante clasp (fold-over buckle). To change the strap: 1) Open the deployante by pressing the side levers; 2) Gently extract the strap from the case; 3) Insert the new strap through the case lugs, ensuring the 17mm terminals fit perfectly; 4) Close the deployante until you hear a click. If inexperienced, consult Casati Milano for professional fitting at the atelier.

Yes, you may use quality aftermarket straps, provided they respect the 17mm lug width. Casati Milano's artisanal straps are crafted specifically for this measurement, using noble materials such as alligator, calf and shell cordovan. Always verify that the terminals are 17mm before purchase.

A quality leather strap (alligator, vegetable-tanned calf or shell cordovan) typically lasts 4-6 years with regular wear, provided ordinary maintenance is observed. Alligator and calf age elegantly, developing patina; shell cordovan improves over time. Casati Milano offers an 18-month warranty on manufacturing defects. Periodic cleaning and protection from excessive moisture significantly extend strap lifespan.
