Datejust 31 278289RBR-0018— lug 16mm

The lug width of the Rolex Datejust 31 278289RBR-0018 is 16mm. This measurement should be taken using a digital calliper placed between the inner walls of the two lugs. Selecting a strap that matches this precise dimension is essential to ensure a proper fit and avoid lateral play.

For the Rolex Datejust 31 278289RBR-0018 in white gold with a diamond-set bezel, a square-scaled alligator strap with a polished finish is the most formally coherent choice. Shell cordovan offers an outstanding patina and superior durability, while vegetable-tanned calf leather suits those who appreciate natural ageing. A white gold buckle or deployant clasp completes the pairing.

The strap on the Rolex Datejust 31 278289RBR-0018 is removed using a springbar tool to compress the 16mm spring bars connecting the strap to the lugs. Press each spring bar inward towards the lug and slide the strap out laterally. It is advisable to work on a soft surface to protect the white gold case. Fitting a new strap is performed in reverse order.

The lifespan of a leather strap on the Rolex Datejust 31 278289RBR-0018 depends on the material and maintenance. A high-quality alligator strap, with regular use and careful protection from moisture, typically lasts between three and five years before showing significant wear. Shell cordovan offers greater longevity due to its dense fibre structure. Prolonged contact with water and perspiration should be avoided, and the strap should be stored away from direct sunlight.
