FAQ
What is the lug width of the Rolex Datejust 31 ref. 178313-0062?
The Rolex Datejust 31 reference 178313-0062 has a lug width of 16mm. This measurement is taken internally between the two lugs using a calliper, and is specific to the Datejust 31 family — distinct from the 20mm of the Datejust 36 and the 13mm of the Datejust 28. Any aftermarket strap must measure 16mm at the lug end to ensure a proper fit.
What is the best strap for the Rolex Datejust 31 178313-0062?
For the Datejust 31 178313-0062, with its two-tone stainless steel and yellow gold case, a vegetable-tanned alligator strap in cognac or bordeaux tones best complements the precious metal elements. Shell cordovan is ideal for formal settings, while smooth calf leather in neutral shades offers everyday versatility. For a more contemporary look, a NATO strap with a gold thread on a navy background is a functional and stylish alternative.
How do you change the strap on a Rolex Datejust 31?
To replace the strap on a Datejust 31, you need to remove the spring bars — the cylindrical pins securing the strap to the case — using a spring bar tool or a forked screwdriver. Rolex spring bars have a diameter of approximately 1.5mm. Work on a soft surface to avoid scratching the case, and ensure the replacement spring bars are the correct length (approximately 20mm for this reference) before fitting the new strap.
Are there aftermarket straps compatible with the Rolex Datejust 31 178313-0062?
Yes, there is a wide range of aftermarket straps compatible with the Rolex Datejust 31 178313-0062. The essential requirement is a 16mm lug width. Milano Straps offers handcrafted straps in alligator, calf leather, shell cordovan and technical materials, with standard or tapered ends (to 14mm), all compatible with original Rolex spring bars. Both classic buckle and deployant clasp options are available.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on material quality and daily care. A high-quality alligator or shell cordovan strap with vegetable tanning can last between 3 and 6 years with regular wear, developing a personal patina over time that enriches its character. It is advisable to rotate between several straps, avoid prolonged exposure to sweat and water, and occasionally apply a neutral conditioner for fine leathers.
