Cellini 50525-0015— lug 20mm

The lug width (ansa width) of the Rolex Cellini 50525-0015 is precisely 20mm. This measurement refers to the internal distance between the two lugs where the strap attaches to the case. It is essential to verify this dimension before ordering an aftermarket strap to ensure complete compatibility. An incorrect measurement would result in a strap that is either loose or impossible to insert into the lugs.

For the Cellini 50525-0015, we recommend authentic alligator with natural grain as the primary choice, as it dialogues perfectly with the sober elegance of the 39mm rose gold case. If you prefer softer feel and multi-generational durability, Italian calf leather with vegetable tanning represents an excellent selection. Shell cordovan from reputable Japanese tanneries offers a refined compromise between character and flexibility, developing a golden patina that amplifies the watch's value over time.

To change the strap on the Cellini 50525-0015, you will need a specific tool: a spring bar removal tool. Insert the tip of the tool into the thin slot on the spring bar, lift gently to release the bar, then remove the old strap. Install the new 20mm strap by reversing the procedure: insert the spring bar into the lugs and press until you hear a click of secure engagement. If you are not experienced with this procedure, Casati Milano can perform the operation in our atelier with precision guarantee.

Yes, it is absolutely possible to use high-quality aftermarket straps with 20mm lug width on the Cellini 50525-0015. We recommend choosing brands specialised in craftsmanship and certified raw materials — alligator from recognised tanneries, Italian Aniline calf leather, Japanese shell cordovan. A high-quality aftermarket strap, with solid construction and impeccable finishing, does not compromise the watch's value or functionality in any way.

The lifespan of a leather strap depends on construction quality, leather type, and usage. Authentic alligator from a historic tannery, properly maintained, can last 5-8 years of daily wear. Calf leather with vegetable tanning often has even greater longevity (8-10 years). Shell cordovan, due to its natural density, can reach 10-15 years. These timeframes extend considerably if the strap is worn occasionally. The Casati Milano warranty covers 18 months against manufacturing and construction defects.
