Datejust 31 278271-0032— lug 16mm

The Rolex Datejust 31 ref. 278271-0032 features a lug width of 16mm. This measurement is the key specification required when selecting any aftermarket strap — whether leather, rubber, or NATO — to ensure correct fitment without lateral play.

Given the Rolesor Everose case of the Datejust 31, an alligator strap in vegetable-tanned leather in bordeaux or cognac tones is the most coherent choice for formal wear, complementing the warm hues of the Everose gold. For daily use, a box calf strap in brown or black offers durability and versatility. All straps must comply with the 16mm lug width specification.

To replace the strap on the Datejust 31, remove the spring bars securing the strap to the lugs using a fine-tipped springbar tool. Apply gentle lever pressure on the outer lug edge to avoid scratching the case. The replacement spring bars must be calibrated to 16mm to ensure a precise fit with no lateral movement.

Yes. Any strap with a 16mm attachment width and standard spring bars is technically compatible with the Datejust 31. Milano Straps offers a selection of handcrafted straps in alligator, calf leather, shell cordovan and rubber, specifically sized for the 16mm lug width, with a tapered tail to 14mm for optimal ergonomic fit.

The lifespan of a leather strap depends on the material, tanning method and frequency of use. A quality vegetable-tanned alligator strap, with regular use and proper care (kept away from moisture and excessive perspiration), typically lasts between two and four years. Shell cordovan, owing to its dense fibrous structure, tends to be more durable, developing a distinctive patina over time.
