Datejust 31 178384-0060— lug 16mm

The lug width of the Rolex Datejust 31 reference 178384-0060 is 16mm. This measurement refers to the internal distance between the case lugs of the Oyster case and determines compatibility with any aftermarket strap. It is a non-standard size: measuring with a digital calliper before purchasing a replacement strap is always recommended.

For the Datejust 31 178384-0060 in steel and white gold, an alligator strap in vegetable-tanned leather is the first-choice option for formal settings, thanks to its geometric scale texture and natural sheen. Shell cordovan suits those seeking a more discreet patina and a compact surface. Box calf leather is an excellent choice for everyday wear. All options must have a 16mm attachment width.

To replace the strap on a Rolex Datejust 31, the spring bars securing the existing bracelet or strap to the case lugs must be removed. A dedicated springbar tool or fork-tip screwdriver is required. Care must be taken to avoid scratching the white gold surfaces. It is advisable to perform the operation on a soft mat or to entrust the task to a watchmaker.

Yes, high-quality aftermarket straps compatible with the Rolex Datejust 31 178384-0060 are available, provided they feature a 16mm attachment width. Milano Straps offers a selection of handcrafted leather, alligator and other material straps made specifically for this lug size, with finishes suited to the aesthetic register of the steel and white gold case.

The lifespan of a leather strap depends on the material and level of care. A vegetable-tanned alligator strap, properly maintained, can last 3 to 5 years with regular use. Shell cordovan tends to last even longer due to the density of its fibres. Frequent exposure to water and perspiration accelerates deterioration: alternating straps and avoiding leather during water-related or sporting activities is strongly recommended.
