Strap for Datejust 31 Stainless Steel Domed Diamond / Jubilee / Purple - Roman

The Rolex Datejust 31 reference 178344-0002 features 16mm lugs. This measurement is essential when selecting a compatible strap: any strap with a 16mm attachment width will fit correctly between the lugs of this model.

For the Datejust 31 in steel and white gold, an alligator Belly strap with a steel or white gold deployant clasp represents the most coherent pairing with the watch's character. Shell cordovan is an excellent alternative, developing a natural patina that complements the luminosity of the white gold case. The correct strap width is 16mm.

To replace the strap on the Datejust 31, use a double-ended spring bar tool to remove the spring bars securing the strap to the 16mm lugs. Press the retractable pin of the spring bar inward against the lug, slide the strap free, and insert the new strap in the same position. It is advisable to work on a soft surface to protect the case from scratches.

Yes. Any strap with a 16mm attachment width is technically compatible with the Datejust 31 178344-0002. Milano Straps offers a curated selection of handcrafted leather, rubber and nylon straps specifically sized for 16mm lugs, available with standard buckle or deployant clasp.

The lifespan of a leather strap depends on the quality of the hide, frequency of use and level of care. A quality alligator or shell cordovan strap, rotated regularly and kept away from excessive moisture and perspiration, will retain its aesthetic and structural integrity for 3 to 5 years. Milano Straps products carry an 18-month guarantee against manufacturing defects.
