FAQ
What is the lug width of the Rolex Datejust 31 ref. 178271-0001?
The Rolex Datejust 31 ref. 178271-0001 has a lug width of 16mm. This measurement is specific to the 31mm case size and determines aftermarket strap compatibility. It is advisable to verify the internal distance between the lugs with a calliper before purchasing a replacement strap.
Which strap best suits the Rolex Datejust 31 178271-0001 in Everose and steel?
For the Oystersteel and Everose bimetallic combination of the Datejust 31, alligator hornback straps in cognac or dark burgundy tones offer the most coherent aesthetic pairing. Shell cordovan develops a patina that naturally complements the warm tone of rose gold. For everyday wear, vegetable-tanned calf leather in tobacco brown is a robust and versatile option.
How do you change the strap on a Rolex Datejust 31?
The strap on the Datejust 31 is secured to the lugs via 16mm springbars. Replacement requires a springbar tool: insert the forked tip between the strap and lug, compress the springbar and slide it free. The operation can be completed in minutes without a watchmaker, provided care is taken not to scratch the case.
Are there aftermarket straps compatible with the Rolex Datejust 31 ref. 178271-0001?
Yes. Milanostraps.it offers a selection of handcrafted straps with a 16mm lug width, compatible with the Datejust 31 178271-0001. Straps are crafted from premium leathers — alligator, calf, shell cordovan — and curved at the top to follow the Oyster case geometry. Standard length is 110/75mm, adjustable on request.
How long does a leather strap last on a Rolex Datejust 31?
Lifespan depends on material and use. A quality alligator strap, worn regularly but not during sport, maintains structural and aesthetic integrity for 3 to 5 years. Vegetable-tanned calf leather typically lasts 2 to 3 years with daily wear. Avoiding prolonged contact with water, perspiration and perfume significantly extends the leather's life. Milano Straps products carry an 18-month warranty against manufacturing defects.
