FAQ
What is the lug width of the Rolex Datejust 31 reference 278248-0038?
The lug width of the Rolex Datejust 31 278248-0038 is precisely 16mm. This is the space between the two terminal bars on the case where the strap is attached. Accurately measuring this dimension is essential to ensure compatibility with aftermarket straps. To verify it, place a ruler between the two case lugs: you will find exactly 16mm of available space.
What is the best strap for the Rolex Datejust 31 278248-0038 in yellow gold?
For the yellow gold Datejust 31, the choice depends on intended use. Alligator represents the formal option par excellence thanks to its distinctive grain that pairs naturally with the reflective qualities of yellow gold. Vegetable-tanned calf offers natural ageing patina and daily versatility. Shell cordovan guarantees durability beyond five years with a lustre that echoes the precious metal. For summer wear, a quality canvas NATO strap or a rubber deployante clasp allows frequent changes without aesthetic compromise.
How do I change the strap on the Rolex Datejust 31 278248-0038?
Changing the strap on the Datejust 31 requires precision. Use a spring bar tool, positioning it in the small groove on the side of the case lug. Apply gentle inward pressure to compress the spring, then carefully remove the old strap. Repeat for the second lug. Insert the new strap ensuring that the springs click fully into their housings. Should you prefer to avoid hands-on work, Casati Milano offers strap replacement service at their atelier.
Can I use an aftermarket strap compatible with the Datejust 31 278248-0038?
Absolutely. The Datejust 31 with 16mm lugs is compatible with any quality aftermarket strap manufactured for this measurement. Milano Straps offers a extensive range of 16mm straps in alligator, calf, shell cordovan and other carefully selected materials. What matters is verifying that the strap is constructed to proper standards: the terminal ends must fit perfectly into the case lugs without lateral play.
What is the average lifespan of a leather strap for the Rolex Datejust 31 278248-0038?
The lifespan of a leather strap depends on material and usage patterns. Quality vegetable-tanned calf typically lasts 2-3 years with daily wear and proper maintenance. Shell cordovan guarantees longer durability, up to five years or beyond, thanks to the structural density of the fibre. Quality alligator varies between 3-4 years. Regular maintenance—cleaning with a soft damp cloth, avoiding direct water exposure, applying leather balm every six months—significantly extends the useful life of any leather strap.
