Strap for Datejust 31 Stainless Steel/ Yellow Gold / Domed / Champagne - Diamond / Jubilee

The Rolex Datejust 31 reference 278243-0026 features a lug width of 16 millimetres. This measurement is specific to the 31mm case size and differs from the smaller Datejust variant (24mm) and the men's versions (20mm). Always verify the exact measurement before purchasing an aftermarket strap, as an incorrect lug width compromises both aesthetics and security of the timepiece.

The Datejust 31 in Rolesor configuration (stainless steel and yellow gold) achieves peak elegance with alligator straps in cognac or dark brown, which echo the warmth of yellow gold. A contemporary alternative is vegetable-tanned calf leather, which develops natural patina over time. For informal contexts, a black rubber strap offers versatility without stylistic compromise. Avoid saturated colours: the Rolesor belongs to classical tradition.

Changing the strap of a Datejust 31 requires a spring bar tool and moderate manual dexterity. Place the watch on a soft surface, insert the spring bar tool tip into the small hole beneath the lug, carefully lift the internal spring, remove the old strap and insert the new one. Ensure the spring returns to proper position and the strap is centred. We recommend having a qualified professional perform this operation to avoid damage to the case.

Yes, provided the strap is constructed for 16mm lug width. Verify that the leather thickness at the lug slot is appropriate (typically between 3.5 and 4.5mm) and that the deployant clasp housing is compatible. Hand-crafted straps from reputable leather ateliers guarantee superior compatibility and durability compared to mass-produced alternatives. We recommend specialist makers who offer in-house fitting trials and zero-defect production guarantees.

Leather strap longevity depends on material quality, frequency of wear and construction standards. An alligator or shell cordovan crafted with vegetable tanning and hand-stitching can last 5–10 years of daily wear, developing characteristic patina. Vegetable-tanned calf withstands 3–5 years. Quality rubber exceeds 10 years. Critical factors: sun exposure, humidity, perspiration. Monitor the lug slot and clasp—initial failures occur here. Proper maintenance (periodic cleaning, rain protection) significantly extends useful life.
