FAQ
What is the lug width of the Rolex Datejust 31 ref. 178245f-0026?
The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the Rolex Datejust 31 178245f-0026 is 16 millimetres. This dimension is specific to Datejust 31 models in rose gold and represents the standard for elegant ladies' wristwatches. Any strap paired with this reference must respect this tolerance to ensure a perfect fit at the lugs.
Which strap is best suited to the Rolex Datejust 31 178245f-0026 in Everose gold?
For a Datejust 31 in Everose gold, straps in <a href="/pages/termine-glossario/alligatore">alligator</a> or premium calf leather are the natural choices. Alligator, with its characteristic texture and regular grain, enhances the rosy tone of the gold without competing for visual attention. For more informal occasions, an FKM rubber strap or silk NATO offers versatility whilst maintaining the inherent elegance of the timepiece.
How do you change the strap on a Rolex Datejust 31?
Changing the strap requires a dedicated spring bar tool to release the pins securing the strap to the lugs. Position the Datejust 31 on a soft surface, locate the small hole on the inner side of the lug, insert the tool to press the spring bar inward, and once released, extract the old strap. Repeat on the opposite side, then insert the new strap by pushing the spring bars into the holes until they click into place.
Can I use a compatible aftermarket strap on my Datejust 31 178245f-0026?
Yes, any strap with a <a href="/pages/termine-glossario/misura-ansa">16-millimetre lug width</a> is compatible. However, the construction quality and finish of the strap significantly impact the overall aesthetics. Artisanal straps such as those by Casati Milano, handcrafted in Italian leather with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a>, guarantee superior patina development and durability compared to mass-produced straps.
How long does a leather strap last on a Rolex Datejust 31?
The longevity of a leather strap depends on usage, maintenance, and tannery quality. A premium calf strap typically lasts 3–5 years with daily wear; an <a href="/pages/termine-glossario/alligatore">alligator</a> or <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> strap with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> can reach 7–10 years. The <a href="/pages/termine-glossario/patina">patina</a> that develops over time is considered a mark of authenticity by many collectors, as it testifies to the leather's genuine composition and natural ageing process.
