Strap for Datejust 31 Everose Domed / President / Black Roman

The lug width of the Rolex Datejust 31 178245f-0037 is 16 millimetres. This measurement should be verified using a digital calliper placed perpendicularly across the interior surface of the lug. It is essential not to confuse this measurement with the strap width itself.

Alligator leather in dark brown or mahogany tones represents the most refined choice, establishing chromatic continuity with the champagne dial whilst allowing the Everose gold to emerge with discretion. Vegetable-tanned calf leather is an equally sophisticated alternative, developing an amber patina that mirrors the warmth of rose gold over time.

The strap is removed by disengaging the spring bars positioned within the lugs. It is advisable to use a dedicated spring bar removal tool and operate over a padded surface to prevent scratching the case. If you are inexperienced, consult an authorised service centre or specialised craftsman.

Yes, any strap with a 16mm lug width is compatible with the Datejust 31 178245f-0037. Ensure the strap is sufficiently long for your wrist (typically 85–150mm for the ladies' model) and that the leather quality meets Rolex standards.

Durability depends on the material and daily use. Quality artisanal alligator or shell cordovan lasts 5–7 years with ordinary maintenance (monthly cleaning, conditioning every 6 months). Vegetable-tanned calf resists for 3–5 years. Frequency of use and exposure to water and perspiration accelerate the natural ageing of leather.
