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

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the Rolex Datejust 31 178159-0007 is 16 millimetres. This dimension is the standard measurement for Datejust 31 models and corresponds to the internal diameter of the lugs on the case, where the strap is inserted. It is a specific measurement—not compatible with 14mm or 18mm straps. When purchasing an aftermarket strap, always verify this technical specification to ensure proper fit.

For a Datejust 31 178159-0007 in white gold, <a href="/pages/termine-glossario/alligatore">alligator</a> straps in black or dark brown are the most refined choices. Alligator leather features a subtle grain that complements the brightness of white gold beautifully. Alternatively, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> in burgundy develops a sophisticated patina over time. For a more casual approach, calf leather with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> in honey brown pairs wonderfully with the luminosity of white gold.

The Datejust 31 uses a standard lug system with straight spring bars. To change the strap, position the watch with the caseback facing upwards and locate the two holes on the lugs where the <a href="/pages/termine-glossario/deployante">deployant</a> buckle sits. Use a proper strap removal tool to gently prise the spring bars and remove the original strap. Insert the new strap in the same manner, ensuring the lugs align perfectly and the spring bar clicks into the closed position. If you are unfamiliar with this procedure, consult a professional watchmaker.

Absolutely. High-quality aftermarket leather straps are completely compatible with the Datejust 31 in white gold, provided they meet the 16-millimetre lug width and correct spring bar diameter. Many owners choose bespoke straps to vary the watch's aesthetic or personalise it. Casati Milano, a Milan-based atelier, creates custom-made straps that fit your preferences perfectly. The finest aftermarket manufacturers offer durability and finish comparable to original Rolex straps.

The lifespan of a leather strap depends on frequency of use, climate and leather type. An <a href="/pages/termine-glossario/alligatore">alligator</a> strap with vegetable tanning lasts an average of 3–5 years with daily wear, developing a beautiful patina over time. Shell cordovan, being more robust, reaches 5–7 years. Calf leather with modern treatment lasts 2–3 years. Factors such as perspiration, high humidity and sunlight exposure accelerate wear. An artisanal strap made from premium leather with quality finishing tends to last longer than mass-produced alternatives, thanks to carefully selected materials and conscious construction.
