Frequently asked questions
What is the lug width of the Rolex Datejust 31 ref. 278240-0014?
The lug width of this model is 16 millimetres. It is measured by the internal distance between the strap attachment pins. This dimension is critical for purchasing a compatible strap without mistakes.
What is the best strap for the Rolex Datejust 31 278240-0014?
The choice depends on usage. For formal elegance, we recommend natural alligator or vegetable-tanned calf leather in dark brown tones. For daily versatility, vegetable-tanned calf in black is timeless. For informal contexts, technical fabric NATO offers practicality. Shell cordovan represents the collector's choice that evolves aesthetically over time.
How do you change the strap on a Rolex Datejust 31?
Use a spring bar tool, an instrument with a bifid tip that is inserted perpendicularly beneath the pins. Apply gentle and controlled pressure to release one side, extract the old strap, position the new one by aligning the pins with the case attachments. Verify it is securely fastened on both sides before wearing the watch.
Is there an aftermarket strap compatible with this reference?
Yes. Any strap with 16mm lug width is compatible with the Datejust 31 278240-0014. Milano Straps offers an extensive collection of artisanal straps in this size, customisable for colour, material and closure type (buckle, deployant, passant).
How long does a leather strap last on a watch like this?
A quality leather strap with vegetable tanning or alligator lasts 18-24 months with moderate daily use. Durability depends on sun exposure, humidity and frequency of use. Milano Straps guarantees 18 months against manufacturing defects and can recommend more resistant materials for critical environments.
