Strap for Datejust 31 White Gold Diamond / Pink

The lug width is 16mm, measured precisely between the lugs where the strap attaches to the case. This is the standard dimension for modern feminine Datejust models. A frequent error involves confusing lug width with strap thickness; the 16mm measurement refers strictly to the distance between the case lugs, not to the leather structure itself.

To enhance the cool elegance of white gold, we recommend alligator in vegetable tanning (which develops natural patina over time) or dark brown shell cordovan. Both create visual contrast without chromatic imbalance. For a more contemporary aesthetic, a navy NATO-style calf offers daily versatility whilst maintaining distinction against traditional options.

You will need a quality spring bar tool—this is not an area to economise. Insert the tool into the slot on the lug, gently lift the elastic pin and slide the old strap away from the lug. Repeat on the opposite side. When installing the new strap, ensure the fixing pin is fully seated and parallel to the lug, avoiding rotation that would compromise security. If you are unfamiliar with this procedure, consult an authorised Rolex service centre or specialist watchmaker.

Yes, provided the lug width is precisely 16mm. A high-quality artisanal aftermarket strap does not compromise the value or integrity of the timepiece; conversely, it allows personalisation according to the owner's taste. Verify that the strap is constructed with premium leathers (alligator, cordovan, vat-dyed calf) and features metal lugs (steel, gold, silver) to prevent premature wear of the case spring pins.

This depends on the material and usage patterns. Vegetable-tanned alligator resists 4-6 years with daily wear; shell cordovan 5-8 years thanks to its superior fibre structure; classic calf leather 3-4 years. Humidity, chlorine and direct sunlight reduce lifespan significantly. Basic maintenance—monthly cleaning with a dry cloth, avoiding swimming pools—substantially extends strap life. Many Rolex owners change straps every 2-3 years for aesthetic reasons rather than structural failure.
