FAQ
What is the lug width of the Rolex Datejust 31 278241-0004?
The Rolex Datejust 31 reference 278241-0004 features a lug width of 16mm. This measurement is specific to the 31mm Datejust case and requires straps with correctly shaped ends compatible with the curvature of the Oyster lugs on this model.
What is the best strap for the Rolex Datejust 31 278241-0004?
For the Everose and steel Datejust 31, alligator leather in burgundy or tobacco brings out the warmth of the rose gold bezel. Shell cordovan in cognac offers an exceptionally compact grain and natural lustre. For everyday wear, a vulcanised rubber strap provides durability without aesthetic compromise.
How do you change the strap on a Rolex Datejust 31 278241-0004?
Replacing the strap on the Datejust 31 requires a fine-tipped spring bar tool to remove the 1.5mm spring bars housed within the lugs. It is advisable to work on a soft surface to protect the case finish. If in doubt, entrust the operation to a watchmaker or the Casati Milano fitting service.
Are there aftermarket straps compatible with the Rolex Datejust 31 278241-0004?
Yes. Milanostraps.it offers a curated selection of 16mm aftermarket straps compatible with the Datejust 31 278241-0004, handcrafted in Italy. It is essential to select straps with curved ends to ensure a proper fit with the Oyster lugs and maintain the aesthetic integrity of the watch.
How long does a leather strap last on a Rolex Datejust 31?
The longevity of a leather strap depends on the material and frequency of wear. A quality alligator strap, kept away from water and perfume, typically lasts 2 to 4 years with regular use. Shell cordovan, owing to its dense fibre structure, tends to offer superior durability. Casati Milano straps come with an 18-month warranty against manufacturing defects.
