Strap for Datejust 31 White Gold Fluted / President / Pink Roman

The lug width of the Rolex Datejust 31 178279-0068 is 16 millimetres. This measurement corresponds to the width of the band connecting the case to both lugs, and it is the critical parameter for ensuring compatibility with any aftermarket strap. A strap of different width will not fit the case correctly.

Alligator remains the canonical choice for the Datejust 31 in white gold, owing to its fine grain and its capacity to develop an extraordinary patina over time. Shell cordovan offers a sophisticated alternative with greater thickness and natural lustre, whilst vegetable-tanned calf leather allows for a soft, deep patina that evolves with age. The selection depends on personal preferences regarding texture and maintenance.

Changing the strap on a Datejust 31 requires the use of specialised tools: a spring bar remover or a delicate watchmaker's lever. After positioning the watch on a soft surface, insert the tool into the lateral recesses of the case, exert gentle pressure to loosen the lug pin, and extract the old strap. The reverse operation ensures installation of the new one. To avoid damage, we recommend delegating this operation to a professional watchmaker.

Any strap with a 16-millimetre lug width is compatible with the Datejust 31 178279-0068. At Milano Straps, we offer a selection of straps in alligator, shell cordovan, calf leather and rubber, crafted by hand with personalised lugs and deployant clasps in steel or precious metals. Compatibility is guaranteed as long as the lug width corresponds to 16mm.

The longevity of a leather strap depends on frequency of wear, climate and material quality. An alligator or shell cordovan of excellent craftsmanship, worn daily in temperate conditions, maintains structural integrity for 5–7 years before requiring replacement. Factors such as high humidity, prolonged sun exposure and perspiration accelerate wear. Regular maintenance with specialist products significantly extends the useful life of the strap.
