Datejust 31 178271-0061— lug 16mm

The lug width of the Rolex Datejust 31 ref. 178271-0061 is 16mm. This measurement represents the distance between the two suspension pins of the case. It is essential to verify this dimension before ordering an aftermarket strap, as not all "Datejust" straps are compatible with this specific width.

For the Datejust 31 two-tone model with mother-of-pearl dial, we recommend straps in dark brown or cognac alligator, or black or brown shell cordovan. These leathers enhance the contrast between the Oystersteel and the Everose gold, maintaining a refined and durable aesthetic over time. A sportier alternative is a dense-weave NATO strap.

To change the strap, you need to extract the suspension pins from the case. We recommend using a professional spring bar tool, available from authorised jewellers or at the Casati Milano atelier. If uncertain, it is preferable to consult a certified watchmaker to avoid damage to the case.

Yes, an aftermarket strap with a 16mm lug width is fully compatible from a mechanical standpoint. However, the quality of craftsmanship, the type of leather, and the finish of the suspension pins significantly influence the final aesthetic harmony. It is advisable to choose artisanal straps from specialised manufacturers, such as Casati Milano, to ensure a finish worthy of the watch's value.

The lifespan of a leather strap varies depending on the material and usage. Quality alligator or shell cordovan can last 10-15 years with ordinary maintenance. Vegetable-tanned calf leather lasts 5-8 years. Periodic maintenance (gentle cleaning, protection from water and humidity) significantly extends strap life. Casati Milano straps, thanks to artisanal construction and leather selection, frequently reach 12-18 years of use.
