The Datejust 31 178245f-0014, seen from the bench

The Rolex Datejust 31 reference 178245f-0014 features a 31mm Everose 18kt gold case with a fluted bezel and Jubilee bracelet. It is powered by the Rolex caliber 2235 automatic chronometer movement. The dial is protected by a Cyclops lens magnifying the date window. Water-resistant to 100 meters, the case is 11.5mm thick. The lug width is 16mm, a standard measurement for medium-diameter Datejust models. This measurement is crucial when selecting aftermarket straps for compatibility.

Frequently asked questions

What is the lug width of the Rolex Datejust 31 ref. 178245f-0014?

The lug width of the Rolex Datejust 31 178245f-0014 is 16mm. This measurement is critical for purchasing compatible straps and should be verified with precision before ordering, measured directly between the case lugs.

Which strap is most elegant for the Rolex Datejust 31 178245f-0014 in rose gold?

For this Everose 18kt reference, alligator with vegetable tanning represents the optimal choice. A medium brown or cognac alligator creates tonal harmony with the case and develops natural patina over time. Alternatively, fine-grain calf in grey tones or shell cordovan offer enduring elegance.

How do you change the strap on a Rolex Datejust 31 ref. 178245f-0014?

Strap replacement requires two specific tools: a thin flathead screwdriver and a removable pin press tool. Position the watch with the upper lug facing towards you, locate the pin access hole, and gently push the pin laterally until it exits. Repeat for the lower pin, then insert the new strap. Work on a soft surface to prevent scratches.

Is a high-quality aftermarket strap compatible with the Datejust 31 178245f-0014?

Yes, provided the lug width is precisely 16mm. Straps from specialised manufacturers, crafted in alligator with vegetable tanning or shell cordovan, guarantee structural compatibility and often exceed OEM straps in aesthetic customisation. Verification of technical specifications is essential.

What is the lifespan of a leather strap on a Rolex Datejust 31?

A high-quality artisanal alligator or calf strap, with proper maintenance, lasts between 5 and 8 years of daily wear. Shell cordovan can exceed 10 years. Longevity depends on factors such as cleaning frequency, humidity exposure, and usage patterns: a seasonally-used strap can last decades. Standard manufacturer warranty covers 18-24 months for manufacturing defects.
