The Datejust 31 178274-0022, seen from the bench

The Rolex Datejust 31 178274-0022 features a 31mm Oystersteel case combined with 18-karat white gold, creating a refined contrast that enhances the lugs and caseback without overwhelming the dial. Powered by the COSC-certified Rolex caliber 2235 automatic movement with Perpetual rotor, it displays hours, minutes, seconds, and date via the Cyclops window at 3 o'clock, with approximately 48 hours power reserve. The Oyster case ensures 100-meter water resistance with screw-down caseback and Twinlock crown; the 16mm lug width is standard for this 31mm generation Datejust, distinct from 36mm models (20mm) and Lady models (28mm).

Frequently asked questions

What is the lug width of the Rolex Datejust 31 178274-0022?

The Rolex Datejust 31 reference 178274-0022 has a lug width of 16mm. This measurement should be taken with a digital calliper between the two lower lugs of the case, at the spring bar seat. It is the essential dimension for selecting a compatible strap without play or tension.

What is the best strap for the Rolex Datejust 31 178274-0022?

For the Datejust 31 178274-0022 in steel and white gold, a vegetable-tanned alligator strap is the most coherent choice with the character of the watch: the belly texture complements the two-tone case. Smooth matte calf leather suits daily wear, while shell cordovan offers superior abrasion resistance. The 16mm lug width should taper to 14mm at the keeper for a well-proportioned profile.

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

Strap replacement requires a fine-tipped spring bar tool to compress the spring bar ends within the 16mm lugs. Work laterally at the lug seat, compress and extract the spring bar. The operation is fully reversible and does not require movement intervention. Take care not to scratch the polished or satin-finished lugs of the Datejust 31.

Are there aftermarket straps compatible with the Rolex Datejust 31 178274-0022?

Yes. All 16mm straps with Oyster-case-shaped ends are compatible with the Datejust 31 178274-0022. Milano Straps offers a selection of handcrafted 16mm straps made with terminals shaped to the specific curvature of Rolex lugs, available in alligator, calf leather, shell cordovan and vulcanised rubber, with steel buckle or deployant clasp.

How long does a leather strap last on a Rolex Datejust 31?

Longevity depends on material and use: a well-maintained vegetable-tanned alligator strap lasts between 3 and 5 years with regular wear. Calf leather tends to develop patina in the first few months and has an average lifespan of 2–3 years. Shell cordovan is the most resistant to surface wear. Avoiding prolonged exposure to water, perspiration and direct UV light significantly extends strap life. Milano Straps provides an 18-month warranty against manufacturing defects.
