FAQ
What is the exact lug width of the Rolex Datejust 31 278275-0031?
The lug width of the Rolex Datejust 31 278275-0031 is 16 millimetres. This measurement represents the distance between the upper and lower lug pins on the case. Any compatible strap must respect this dimension to ensure secure installation without forcing or damage.
Which strap material is best suited for the Datejust 31 278275-0031 in Everose gold?
Alligator leather represents the ideal choice to enhance Everose gold: its refined texture and natural patina create unmatched aesthetic harmony. Brown or black calf offers robustness and versatility. Shell cordovan provides durability and a lustre that dialogues elegantly with rose gold. Vegetable-tanned leather is recommended for those desiring a material that ages with visible character.
How do I change the strap on my Rolex Datejust 31 278275-0031?
Strap replacement is performed using a specialised tool to remove the lug pins. It is not complicated but requires care to avoid scratching the gold case. If you are inexperienced, entrust the task to a qualified watchmaker. For a bespoke artisanal strap, Casati Milano can guide you through every phase of realisation.
Is an aftermarket strap compatible with the Datejust 31 278275-0031?
Yes, provided the lug width is exactly 16 millimetres. Straps measuring 14, 18 or 20 millimetres will not install correctly. Artisanal straps crafted to specification guarantee structural compatibility and superior construction quality compared to many mass-market options, preserving your Rolex's value and aesthetics.
How long does a leather strap last on the Rolex Datejust 31 278275-0031?
A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts 5–10 years with daily wear, depending on usage frequency and maintenance care. Leather requires periodic aeration and protection from excessive moisture. An artisanal strap develops patina that evolves over time, making wear a narrative of aesthetics rather than defect.
