FAQ
What is the lug width of the Rolex Datejust 31 ref. 178278-0065?
The lug width (anse) of the Rolex Datejust 31 ref. 178278-0065 is 16 millimetres. This dimension is specific to 31mm women's Datejust models and is determined by the case proportions. It is essential to verify this measurement with a digital calliper before ordering a compatible strap, as even a 1mm deviation would cause mounting issues or excessive structural play.
Which strap material is most suitable for the Rolex Datejust 31 178278-0065 in yellow gold?
For a Datejust 31 178278-0065 in 18k yellow gold, the most coherent materials are alligator (brown or black, for classical restraint), shell cordovan (for rich patina and durability), vegetable-tanned calf leather (for visible colour evolution over time) and cotton NATO (for casual versatility). Alligator remains the conservative and most elegant choice, as its uniform texture does not visually compete with the solid gold case.
How do you change the strap on a Rolex Datejust 31 178278-0065?
Strap replacement requires the use of a specialised tool (spring bar tool) to remove the elastic pins that connect the strap to the case. It is advisable to consult a professional watchmaker or a specialised atelier such as Casati Milano, which possesses the correct tools and expertise to avoid scratching the yellow gold case. Rolex itself recommends strap changes at its authorised service centres.
Can I use an aftermarket compatible strap on my Datejust 31 178278-0065?
Yes, it is possible to use artisanal quality aftermarket straps provided they respect the exact 16mm lug width. Milano Straps offers a collection of 16mm straps designed and manufactured in Italy, featuring premium materials such as alligator, shell cordovan and vegetable-tanned calf. The construction quality and use of natural leather ensure aesthetic and functional coherence with the value of the Rolex.
What is the average lifespan of a leather strap on a Rolex Datejust 31 178278-0065 worn daily?
A high-quality artisanal leather strap (alligator, shell cordovan or vegetable-tanned calf) worn daily has an average lifespan of 3-5 years, depending on intensity of use, moisture exposure and maintenance. Noble materials such as shell cordovan tend to last longer, developing a prized patina. Casati Milano provides an 18-month warranty against manufacturing defects and is available for repairs and replacements of wear finishes.
