Strap for Datejust 31 White Gold Diamond / President / Silver Roman

The lug width of the Rolex Datejust 31 ref. 178159-0052 is 16mm. This is a non-standard size compared to more common calibres: always verify with a digital calliper between the lugs before purchasing an aftermarket strap.

For the Datejust 31 in white gold, a glossy black alligator or vegetable-tanned box calf leather strap best matches the formal register of the piece. A white gold deployant clasp completes the pairing without visual discontinuity between leather and metal.

To replace the strap on a Datejust 31, use a fine-tipped spring bar tool. The 16mm lugs accommodate standard spring bars. Work carefully to avoid scratching the white gold case edge: using plastic or silicone lug protectors is strongly recommended.

A quality leather strap — alligator or vegetable-tanned calf — on a Datejust 31 typically lasts between 2 and 4 years with daily wear, depending on exposure to perspiration and moisture. The Casati Milano warranty covers manufacturing defects for 18 months. Rotating between two straps significantly extends the life of both.
