Strap for Datejust 31 Yellow Gold Diamond / President / Champagne Diamonds Rubies

The Rolex Datejust 31 reference 178158-0070 features a lug width of 16 millimetres. This measurement is specific to this model and must be verified with precision before purchasing an aftermarket strap. Correct measurement is taken inside the lugs, perpendicular to the case, using a digital calliper with 0.1mm accuracy.

For the yellow gold Datejust 31 with 31mm diameter, we recommend alligator niloticus in brown tones (cognac, dark brown), vegetable-tanned calf leather, or aged shell cordovan. Alligator creates a natural dialogue with the brilliance of gold; vegetable-tanned calf develops a patina that mirrors the metal's evolution over time.

Remove the lateral metal spires (spring bars) using a dedicated Y-shaped tool. Position the watch on a soft surface, compress the spring gently to free the pin, and insert the new strap beneath the spring. Professional assistance is recommended to prevent damage to the case.

Yes, it is possible to use certified quality aftermarket straps, provided they respect the 16mm lug width and the spring diameter is compatible with the case. Noble leathers such as alligator, shell cordovan and vegetable-tanned calf guarantee aesthetics and durability consistent with Rolex standards.

A noble leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts an average of 3–5 years with daily wear, if properly maintained. Longevity depends on sun exposure, humidity and cleaning frequency. Leather deteriorates naturally; as it ages, it develops patina and requires periodic replacement to maintain original elegance.
