Strap for Datejust 31 Everose Domed / President / Black MOP

The lug width of the Rolex Datejust 31 178245f-0015 is 16 millimetres. This dimension is standard across all Datejust 31 models and is measured perpendicularly between the internal poles of the spring bar tube. Verification of this measurement to millimetre precision is crucial when sourcing an aftermarket strap, as a deviation of 0.5 mm will result in poor adhesion or vibration.

Alligator leather represents the most formal and elegant choice for a Datejust 31 in Everose, owing to its regular texture and the patina that develops over time. For daily wear, aniline calf offers superior softness and thermal adaptability. Those seeking maximum versatility will opt for black vulcanised rubber or shell cordovan, both materials that age gracefully without aesthetic compromise.

Changing the strap on a Datejust 31 requires a dedicated spring bar removal tool. After positioning the watch on a protective surface, apply gentle pressure to the spring bar from inside the case, lifting until it disengages. Extract the original strap and insert the new one, ensuring the tube is perfectly perpendicular to the case. This procedure demands care to avoid scratching the rose gold case.

Yes, a high-quality aftermarket strap does not compromise the watch's value, provided it is crafted from noble materials (alligator, calf, shell cordovan) and maintains aesthetic coherence with the case. Indeed, a bespoke strap from a specialised atelier may enhance your enjoyment and perception of individuality. Retaining the original Rolex strap is nonetheless advisable for authentication documentation.

A superior-quality alligator strap, vegetable-tanned, typically lasts between 5 and 8 years with daily use and appropriate maintenance (regular cleaning, protection from excessive moisture and direct heat). Aniline calf tends to wear more quickly, within 3 to 5 years, due to finer fibre structure. Shell cordovan, given its natural composition, can exceed 10 years if properly maintained. Vulcanised rubber offers durability comparable to aniline calf but with superior resistance to atmospheric agents.
