Frequently asked questions
What is the lug width of the Rolex Datejust 31 ref. 178275f-0032?
The Rolex Datejust 31 ref. 178275f-0032 has a lug width of 16mm. This measurement is taken between the two lugs, flush against the case, and is critical for selecting a compatible strap that fits without forcing or risking scratches on the Everose gold case.
What is the best strap for the Rolex Datejust 31 178275f-0032?
For the Everose gold case of the Datejust 31 178275f-0032, straps in vegetable-tanned alligator or shell cordovan are the most coherent choice: their natural grain and developing patina complement the quality of the precious material. For more active daily use, a vulcanised rubber strap in 16mm preserves the Oyster water resistance without aesthetic compromise.
How do you change the strap on a Rolex Datejust 31?
The Datejust 31 strap is secured to the lugs via 16mm spring bars. Removal requires a bifurcated spring bar tool to compress the spring bar ends and release the strap. It is advisable to work on a soft surface to protect the case and, if in doubt, to entrust the operation to a watchmaker or the Casati Milano atelier.
Are there aftermarket straps compatible with the Rolex Datejust 31 178275f-0032?
Yes, numerous aftermarket straps in 16mm are compatible with the Datejust 31 178275f-0032, provided they respect the exact 16mm lug width and the case-end geometry. Milano Straps offers handcrafted straps manufactured to a tolerance of ±0.2mm, available in leather, alligator, cordovan and rubber, with pin buckle or deployant clasp.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on the material and care: a quality vegetable-tanned alligator strap, used on rotation and kept away from prolonged moisture, retains its structural and aesthetic integrity for 3 to 5 years. Shell cordovan, owing to the density of its fibres, resists buckle wear particularly well. Milano Straps backs its straps with an 18-month warranty against manufacturing defects.
