FAQ
What is the lug width of the Rolex Datejust 31 ref. 178159-0059?
The lug width of the Rolex Datejust 31 ref. 178159-0059 is 16mm. This is a non-standard measurement compared to the Datejust 36 or 41, and is specific to the 31mm case size. To verify it, measure the internal distance between the two lugs at the strap attachment point using a digital calliper.
What is the best strap for the Rolex Datejust 31 178159-0059 in white gold?
For an 18kt white gold case, the most appropriate strap is a vegetable-tanned alligator belly with a white gold or silver PVD deployant clasp. Shell cordovan offers a formal, compact surface as an alternative. Smooth calf leather with contrast stitching is a versatile option between formal and everyday wear. NATO straps with standard metal keepers are not recommended due to the short lug geometry of this model.
How do you change the strap on a Rolex Datejust 31?
To replace the strap on a Rolex Datejust 31, the spring bars connecting the original bracelet to the case lugs must be removed. Use a fine-tipped springbar tool inserted into the lug hole to compress the bar. When working with white gold lugs, it is advisable to protect the surface with soft cloth or low-tack tape to prevent scratching. The replacement strap must be 16mm wide.
Are there aftermarket straps compatible with the Rolex Datejust 31 178159-0059?
Yes, high-quality aftermarket straps are available specifically made for the 16mm lug width of the Datejust 31. Milano Straps offers a selection of alligator, calf and shell cordovan straps cut to 16mm, supplied with spring bars. Artisan production ensures the correct dimensional tolerance — critical on precious metal cases where an ill-fitting strap can damage the lugs.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on the material and usage habits. A quality vegetable-tanned alligator strap, rotated with at least one other strap, typically lasts 3–5 years before showing significant wear on the underside. Shell cordovan, owing to the density of its fibres, is more resistant to moisture and can last over 5 years. Smooth calf leather is more vulnerable to perspiration and requires more frequent replacement. A deployant clasp reduces mechanical stress on the strap compared to a pin buckle, extending its service life.
