FAQ
What is the lug width of the Rolex Datejust 31 278288rbr-0020?
The lug width of the Rolex Datejust 31 278288rbr-0020 is 16mm. This measurement refers to the gap between the case lugs and is specific to this reference: it differs from other Datejust diameters, such as the 36mm (20mm) or 41mm (21mm). To confirm strap compatibility, it is advisable to measure directly on the watch using a digital calliper.
What is the best strap for the Rolex Datejust 31 278288rbr-0020?
For the Datejust 31 in yellow gold, a vegetable-tanned alligator strap is the most coherent choice given the watch's aesthetic register. The bombé grain of Louisiana alligator belly complements the polished gold case surfaces. Alternatively, shell cordovan develops a rich patina over time and resists deformation exceptionally well. For less formal wear, fine-grain calf leather or a silk NATO strap are suitable options. The attachment width is 16mm.
How do you change the strap on a Rolex Datejust 31?
To replace the strap or bracelet on the Rolex Datejust 31, a spring bar tool is required. The 1.8mm spring bars securing the strap to the lugs are removed by applying gentle leverage with the tool into the small slot on the side of each lug. The process does not require case disassembly and does not compromise water resistance, provided the crown and caseback remain undisturbed.
Are there aftermarket straps compatible with the Rolex Datejust 31 278288rbr-0020?
Yes. The Datejust 31 278288rbr-0020 features 16mm lugs, a width for which a wide range of quality aftermarket straps are available. Milano Straps offers a curated selection of handcrafted 16mm straps in alligator, shell cordovan and calf leather, fitted with 1.8mm stainless steel spring bars compatible with Rolex original lugs. Each strap is calibrated to ensure a precise fit with the case geometry.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on the material, maintenance and frequency of use. A quality vegetable-tanned alligator strap, kept away from excessive perspiration and water exposure, can last between 3 and 7 years while retaining structural and aesthetic integrity. Shell cordovan is even more resistant to deformation. Regular application of a leather conditioner and rotation between multiple straps significantly extends the life of the piece.
