Strap for Datejust 31 Rose Gold / Domed / White - Roman / President

The Rolex Datejust 31 ref. 278245-0018 has a lug width of 16mm. This measurement is specific to the 31mm case size and differs from the 19mm of the Datejust 36 and the 20mm of the Datejust 41. It is essential to use aftermarket straps designed precisely for 16mm to ensure a correct and secure fit.

For the Datejust 31 278245-0018 in Everose gold, a vegetable-tanned alligator strap is the most aesthetically coherent choice: cognac, bordeaux or havana tones complement the warm hues of Everose gold. Alternatively, shell cordovan offers a compact grain and refined stiffness. For daily or light sports use, a vulcanised rubber strap with a leather-like texture is practical without compromising the formal reading of the gold case.

To change the strap on the Datejust 31, you need to remove the spring bars that secure the original bracelet to the case lugs. Use a fine-tipped springbar tool, applying gentle pressure in the designated notch on the lug. Take care not to scratch the case: place the watch on a soft cloth and work under good lighting. The new 16mm strap fits into the same position.

Yes, there are many aftermarket straps compatible with the 16mm lug width of the Datejust 31 278245-0018. milanostraps.it offers a selection of handcrafted straps in leather, rubber, and alternative materials, all made for this specific width. For an optimal fit, it is also important to verify the correct short and long taper lengths for your wrist size, as well as the curvature of the strap end.

The lifespan of a leather strap depends on the quality of the hide, the tanning process, and usage habits. A quality vegetable-tanned alligator strap, with regular but not intensive wear, typically lasts between two and five years. Shell cordovan, thanks to its dense fibrous structure, tends to last longer whilst developing a distinctive patina. Frequent exposure to water, perspiration, and UV rays accelerates deterioration: it is advisable to rotate between at least two straps.
