Strap for Datejust 31 White Gold Diamond / Pink - Roman

The lug width is precisely 16 millimetres. This dimension is standard across all Datejust 31 models and represents the distance between the two lugs where the strap attaches. Verifying this measurement before purchasing an aftermarket strap is essential, as an incompatible lug width compromises both aesthetics and wearing comfort.

Natural alligator is the most recommended choice: its silky texture and balanced grain create a harmonious dialogue with white gold and enhance the rainbow diamond bezel. Shell cordovan with vegetable tanning, developing a patina over time, and high-quality calf leather in natural tones are equally excellent alternatives. For sporadic use, premium rubber or woven NATO straps maintain elegance without compromise.

The most reliable method is to measure the internal distance between the two metal lugs using a digital calliper or ruler. Position the zero at the centre of the first lug's internal edge and measure to the centre of the second lug's internal edge. For the Datejust 31, this measurement will be exactly 16mm. If uncertain, consult the official Rolex warranty certificate.

Yes, provided the lug width is precisely 16 millimetres and construction quality is certified. Beware of generic straps: manufacturing tolerances outside Rolex specifications often result in micro-deviations causing play and accelerated wear. A bespoke custom strap ensures perfect fit, superior durability, and materials selection consistent with the watch's value.

Longevity depends on material quality, daily usage, and climate conditions. Premium alligator supports 3–5 years of regular wear before requiring maintenance. Vegetable-tanned shell cordovan often lasts longer, developing a coveted patina over time. Calf leather requires more frequent conditioning every 6–12 months. Rubber straps, if properly stored, maintain integrity for 5–7 years. Environmental factors such as perspiration, moisture, and temperature fluctuations accelerate ageing.
