Frequently asked questions
What is the lug width of the Rolex Datejust 31 178341-0013?
The lug width of the Rolex Datejust 31 178341-0013 is 16 millimetres. This technical specification represents the distance between the two metal lugs on the case and is critical for strap compatibility. Verifying this measurement ensures that the strap fits perfectly to the case pins without lateral play.
What is the best strap for the Rolex Datejust 31 178341-0013?
For the Datejust 31 178341-0013, alligator leather represents the most refined choice: its regular grain enhances the rose gold finish. Calf leather offers versatility for daily and formal wear, whilst shell cordovan allows the development of a unique temporal patina. The choice depends on intended use and personal chromatic preferences.
How do you change the strap on a Rolex Datejust 31?
Changing the strap requires the use of a specific spring bar tool. Position the watch on a stable surface, insert the tool into the slot beneath the lug to compress the internal elastic pin, then remove the old strap. Repeat the operation on the other lug. Insert the new strap pins into the case lugs and verify that the pin clicks correctly into position.
Is an aftermarket strap compatible with the Datejust 31 178341-0013?
Yes, any strap with a 16-millimetre lug width is compatible with the Datejust 31 178341-0013. Bespoke artisanal straps represent a quality alternative to original Rolex straps, offering aesthetic customisation and selected materials. It is essential to verify that the pins are appropriate for the lug width.
What is the lifespan of a leather strap on a Rolex Datejust 31?
A high-quality leather strap, with vegetable tanning or shell cordovan, has an average lifespan of 3-5 years with daily use. Longevity depends on factors such as sun exposure, humidity, cleaning frequency and intensity of use. Regular maintenance and occasional application of protective creams significantly extend the life of the strap.
