FAQ
What is the lug width of the Rolex Datejust 31 178279-0064?
The Rolex Datejust 31 reference 178279-0064 has a lug width of 16mm. This measurement is fixed by the geometry of the 18-carat white gold case and remains consistent across all dial variants of this reference. When purchasing an aftermarket strap, always measure the internal lug width with a digital calliper to ensure a proper fit.
What is the best strap for the Rolex Datejust 31 178279-0064?
For the Datejust 31 in white gold, a lacquered alligator strap in 16mm is the most coherent choice given the formal aesthetic of the case. The regular belly-scale grain complements the metallic surface without overwhelming it. Alternatively, shell cordovan or box-calf leather tanned using vegetable methods offer a characterful patina suited to more versatile daily wear. A deployant clasp in white gold or brushed steel is the recommended closure.
How do you change the strap on a Rolex Datejust 31 178279-0064?
To replace the strap on the Datejust 31 178279-0064, the spring bars connecting the strap to the case lugs must be removed. A fork-style spring bar tool is inserted into the side slot of the lug to compress the spring and release the bar. Care should be taken to avoid scratching the white gold case: a protective cloth placed beneath the case is strongly recommended during the procedure.
Are there aftermarket straps compatible with the Rolex Datejust 31 178279-0064?
Yes. Any strap with a 16mm lug width and standard spring bars is technically compatible with the Rolex Datejust 31 178279-0064. Milanostraps.it offers a curated selection of handcrafted 16mm straps in alligator, calf leather, shell cordovan and nylon made by Casati Milano, also available as bespoke commissions with direct leather selection at the atelier. Geometric compatibility is guaranteed; a white gold clasp is recommended for visual coherence with the original case.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on leather quality, tanning method and daily use. A high-quality alligator or shell cordovan strap, maintained regularly with leather conditioner and allowed to dry after moisture exposure, can last between 3 and 7 years while retaining structural integrity and a well-kept appearance. Vegetable-tanned leathers develop a unique personal patina over time, enhancing their aesthetic value. Prolonged exposure to perspiration, water and perfume accelerates leather degradation.
