FAQ
What is the lug width of the Rolex Datejust 31 ref. 178158-0086?
The lug width of the Rolex Datejust 31 ref. 178158-0086 is 16mm. This measurement should be taken with a digital calliper positioned inside the lugs, against the case, to obtain the precise internal dimension required for strap selection.
What is the best strap for the Rolex Datejust 31 178158-0086 in yellow gold?
For an 18k yellow gold case, a vegetable-tanned alligator strap — in a glossy or semi-glossy finish — is the classic dress watch choice. Shell cordovan develops a rich patina over time and offers a compelling alternative. A yellow gold deployant clasp is recommended to preserve the strap's geometry and protect the lugs from wear.
How do you change the strap on a Rolex Datejust 31?
The Datejust 31 uses spring bars with a 1.5mm diameter. To replace the strap, use a fine-tipped spring bar tool to compress the spring bar within the lug and slide the strap free. Rest the case on a soft cloth to avoid scratching the bezel or caseback during the operation.
Are there aftermarket straps compatible with the Rolex Datejust 31 178158-0086?
Yes. Any strap with a 16mm attachment width and standard 1.5mm spring bars is compatible. Milano Straps offers handcrafted straps in alligator, calfskin, shell cordovan and other materials, made to measure for this reference, with a choice of buckle or deployant clasp.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on material quality and maintenance. A high-grade alligator or shell cordovan strap, worn daily and properly cared for (periodic conditioning, protection from prolonged moisture), retains its structural and aesthetic integrity for 3 to 5 years. Milano Straps provides an 18-month warranty against manufacturing defects.
