Frequently asked questions
What is the lug width of the Rolex Datejust 31 ref. 178271-0058?
The Rolex Datejust 31 reference 178271-0058 has a lug width of 16mm. This measurement, taken internally between the two lugs at the strap attachment point, is the critical parameter for selecting any compatible aftermarket strap. A strap of incorrect width will not seat properly and may cause damage to the steel or Everose gold lug surfaces.
What is the best strap for the Rolex Datejust 31 178271-0058 with a mother-of-pearl dial?
For the 178271-0058 featuring a mother-of-pearl dial and Everose gold inserts, a vegetable-tanned alligator strap in bordeaux, cognac or tobacco brown tones is the most coherent choice for the watch's formal register. Shell cordovan offers a more hardwearing alternative for intensive daily use. For sportier contexts or humid climates, a 16mm vulcanised rubber strap provides both durability and visual cleanliness.
How do you change the strap on a Rolex Datejust 31 ref. 178271-0058?
Replacing the strap on the Datejust 31 requires a spring bar tool or a dedicated lever tool to remove the 16mm spring bars housed within the lugs. The operation is straightforward but demands care to avoid scratching the Everose gold or polished steel surfaces. It is advisable to work on a soft surface and, if in any doubt, to entrust the task to a watchmaker or to the Casati Milano atelier.
Are there aftermarket straps compatible with the Rolex Datejust 31 178271-0058?
Yes, the aftermarket offers a wide selection of straps compatible with the Datejust 31's 16mm lug width. Milanostraps.it provides a curated range of handcrafted 16mm straps in various materials and finishes, designed with proportions suited to the 31mm case diameter. Always verify the strap length — standard or short — against your wrist circumference before ordering.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on the material, tanning method and conditions of use. A high-quality vegetable-tanned alligator strap, properly maintained and kept away from prolonged contact with water and perspiration, can last between three and six years while developing a distinctive personal patina. Shell cordovan straps tend to show greater resistance to surface wear. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
