Datejust 31 178243-0058— lug 16mm

The Rolex Datejust 31 reference 178243-0058 has a lug width of 16mm. This measurement should be taken with a digital calliper inside the lugs, at the point of contact with the strap, to ensure accurate aftermarket fitment.

For the 178243-0058 in steel and yellow gold with a mother-of-pearl dial, the most suitable straps are alligator in cognac or honey tones (to complement the 18k gold) or vegetable-tanned calfskin in taupe or hazelnut (to balance the mother-of-pearl). Shell cordovan is a distinguished alternative with a natural patina. All straps must have a 16mm lug width.

To replace the strap on a Datejust 31, use a fine-tipped springbar tool to remove the spring bars from the lugs. Work on a soft cushion to protect the case. Rolex spring bars have a specific diameter: when replacing them, use high-quality bars of equivalent specification with the correct length for the 16mm lug.

Yes, numerous aftermarket straps are compatible provided they conform to the 16mm lug width. Milano Straps offers a selection of handcrafted straps in 16mm, made to order or available online, in leather, alligator, shell cordovan and rubber, with steel or gold-plated buckles and deployant clasps compatible with the bi-material aesthetic of the Datejust 31.

The lifespan of a leather strap depends on material quality and frequency of wear. A high-quality alligator or shell cordovan strap with vegetable tanning and hand-finished edges can last between 3 and 7 years with ordinary care. Avoid prolonged contact with water and perspiration, rotate between multiple straps where possible, and occasionally apply a neutral conditioner for fine leathers.
