Pearlmaster 80318-0054— lug 14mm

The Rolex Pearlmaster 80318-0054 has a lug width of 14mm. This measurement should be taken with a calliper between the two lugs of the case — where the spring bar is inserted — to ensure a precise fit for any replacement strap.

For an 18-carat yellow gold case measuring 29mm, an alligator strap in vegetable-tanned leather in cognac or bordeaux is the most aesthetically coherent choice. The symmetrical grain of the alligator complements the worked surfaces of the gold without overwhelming them. Shell cordovan is a refined alternative for those seeking a strap that develops a rich patina over time.

The integrated bracelet of the Pearlmaster is removed using dedicated precision spring bar tools. A fork-type spring bar tool is recommended to avoid scratching the yellow gold lugs. Given the precious nature of the material, entrusting this operation to a watchmaker or a specialist atelier such as Casati Milano ensures a risk-free fitting.

Yes. Aftermarket straps with a 14mm lug width are compatible with the Rolex Pearlmaster 80318-0054, provided they precisely match the 14mm lug width and use a spring bar of the correct diameter. Milanostraps.it offers a curated selection of handcrafted 14mm straps made specifically for this case size.

A quality leather strap — such as alligator or vegetable-tanned calfskin — typically lasts between 2 and 4 years with regular wear, depending on exposure to perspiration, water, and UV light. Vegetable-tanned leather develops a characteristic patina over time that enhances its aesthetic value. Casati Milano straps carry an 18-month warranty against manufacturing defects.
