The Datejust 31 178248-0088, seen from the bench

The Rolex Datejust 31 178248-0088 in 18-karat yellow gold features a 31mm case designed for smaller wrists while maintaining presence through the density of the metal. Powered by the COSC-certified Rolex calibre 2235 automatic movement, it offers date quick-set at 3 o'clock and water resistance to 100 meters. The lug width is 16mm, a specification typical of vintage compact Datejust models and contemporary women's watches.

Frequently asked questions

What is the lug width of the Rolex Datejust 31 178248-0088?

The Rolex Datejust 31 reference 178248-0088 is fitted with lugs of 16mm width. This measurement is specific to compact-cased Datejust models and is not standard across the contemporary Rolex catalogue. To verify strap compatibility, measure the distance between the two lug holes on the case: it must be exactly 16mm.

What type of strap is most recommended for the Datejust 31 178248-0088 in yellow gold?

For the Datejust 31 178248-0088 in yellow gold, Nile alligator in cognac or medium brown represents the most versatile and elegant choice. The regular grain of the leather dialogues harmoniously with the case polish without visual competition. Alternatively, Taurillon calf with vegetable tanning offers a more pronounced texture and develops an authentically aged patina over time. Those seeking stronger character might consider shell cordovan in deep burgundy, which creates a sober contrast whilst maintaining formality.

How do I change the strap on a Rolex Datejust 31?

Changing the strap on a Rolex Datejust 31 requires extraction of the spring bars from the lug holes on the case. Use a quality spring bar tool to avoid scratching the case: insert the tip into the bar slot, apply gentle pressure to release the internal spring, then extract the old strap. Align the new strap holes with the lugs, then reinsert the bars until you hear or feel the click. If inexperienced, entrust the task to a specialised watchmaker. Casati Milano offers this service at its Milan atelier.

Can I use an aftermarket-compatible strap with the Datejust 31 178248-0088?

Certainly. Any quality strap manufactured with a 16mm lug width is compatible with the Datejust 31 178248-0088. Handcrafted straps in alligator, calf, shell cordovan or natural vulcanised rubber offer construction quality and material standards superior to standard factory straps. Milano Straps curates a specialised collection of aftermarket straps in 16mm, all crafted with meticulous finishing. A bespoke personalised strap from Casati Milano guarantees perfect fit to your specific case.

What is the expected lifespan of a leather strap for the Datejust 31?

Leather strap longevity depends on material quality, frequency of wear and maintenance practice. An artisanal strap in Nile alligator or Taurillon calf with vegetable tanning has an estimated lifespan of 3–5 years with daily wear. Nile alligator typically outlasts alternatives due to fibre density. Shell cordovan, being a denser natural membrane, can last 5–7 years. Regular maintenance—thorough drying after moisture exposure, conditioning with natural oils—significantly extends lifespan. Straps crafted by Casati Milano with vegetable tanning age nobly, developing patina that amplifies aesthetic value over time.
