Strap for Datejust 31 White Gold Diamond / President / Silver Diamond

The lug width of the Rolex Datejust 31 178159-0054 is 16 millimetres. This dimension is standard for all 31mm Datejust cases and represents the linear distance between the two lugs of the case. Always verify this measurement before ordering a compatible strap to ensure proper fit.

Alligator remains the most refined choice for the white gold Datejust 31: its natural grain and inherent softness create an elegant contrast with the cool luminosity of white gold. Vegetable-tanned calf leather offers a versatile alternative, developing a patina over time. For daily wear, silicone or rubber straps provide practicality without aesthetic compromise.

Changing the strap on a Datejust 31 requires a specific tool (spring bar tool) and considerable care. Compress the elastic pin beneath the lug, extract it from the case lug, and reposition the new strap. It is advisable to consult a professional watchmaker to avoid scratching the case, especially on white gold.

Any strap with a lug width of 16 millimetres is compatible with the Datejust 31 178159-0054. Milano Straps offers a comprehensive collection of straps in various materials (alligator, calf, rubber, NATO) specifically dimensioned for this lug width, crafted with artisanal care and available both online and through bespoke customisation at the Casati Milano atelier.

The lifespan of a leather strap on a Datejust 31 depends on construction quality and daily wear, typically ranging between 3 and 7 years. Vegetable-tanned leather develops a characteristic patina and may last longer; alligator, if properly maintained, resists extremely well over time. Proper care and protection from saltwater and humidity significantly extend the strap's lifespan.
