Strap for Daytona White Gold Blue Sapphire Strap Sodalite

The lug width of the Rolex Daytona 116589saci-0002 is 20 millimetres. This measurement is standard across all modern Daytona models from the 116xxx reference series onwards. The correct measurement should be taken from lug to lug on the inner distance of the case, not from the base of a traditional buckle.

For the white gold Daytona, alligator leather is the canonical choice, preferably in tones that dialogue with the precious metal (black, brown, or light blonde belly leather). Shell cordovan is a legitimate alternative for those seeking density and organic patina development. Vegetable-tanned calf offers a compromise between luxury and everyday wearability with organic ageing. Rubber or synthetic straps remain functionally compatible but aesthetically distant from the white gold's formal character.

Changing the Daytona strap follows the standard procedure for watches with pass-through lugs: a fine-tipped spring bar tool is used to compress and lift the lug springs, freeing the connecting element. The operation is not recommended without specific tools. Casati Milano can perform the change with artisanal supervision and guidance on compatible materials.

Yes, any strap with a 20-millimetre lug width is mechanically compatible with the Daytona 116589saci-0002. Aesthetic compatibility depends on the material chosen and colour: alligator, shell cordovan, and vegetable-tanned calf are the recommended choices to respect the nobility of white gold. Synthetic straps remain functionally compatible but do not enhance the case's formal qualities.

A natural leather strap (alligator, shell cordovan, or calf) under regular daily wear typically lasts 3–5 years before requiring replacement or professional restoration. Durability depends on exposure to moisture, perspiration, UV rays, and frequency of wear. Vegetable-tanned leather and shell cordovan age by developing patina, while alligator maintains more stable structure. Casati Milano offers an 18-month warranty on manufacturing defects for all artisanal straps.
