Strap for Datejust 31 Stainless Steel Fluted / Jubilee / Pink

The lug width of the Rolex Datejust 31 178274-0012 is 16 mm. This is the internal measurement between the two spring bar pins that hold the strap. Any strap with a 16 mm lug width will be mechanically compatible with this model.

The best strap depends on your usage and personal preference. For classic elegance, we recommend dark brown or cognac alligator. For modern aesthetics, black calf leather with smooth finishing. For versatility, a grey or navy NATO fabric strap. For summer sports, waterproof FKM rubber. The steel-white gold 178274-0012 pairs naturally with cool-toned colours (black, grey, blue).

Changing the strap requires a spring bar tool. Position the watch with the lugs facing you, insert the tool into the hole at the base of the lug to compress the internal pin, remove the old strap and insert the new one in the same manner. If you lack experience, entrust this task to a jeweller or specialised service.

Yes, any strap with a 16 mm lug width is mechanically compatible. However, choose high-quality straps (alligator, vegetable-tanned calf, FKM rubber) to preserve the value and elegance of the watch. A poor-quality strap visually penalises even the most refined Rolex.

A quality leather strap (alligator, calf) typically lasts 3-5 years with regular wear, depending on frequency of use, sun exposure and humidity. Vegetable-tanned leather develops a natural patina that becomes more fascinating over time. With proper care (drying after rain, avoiding chlorine), the lifespan extends further.
