Frequently asked questions

What is the lug width of the Rolex Datejust 36 116231-0069?

The lug width (misura ansa) of the Rolex Datejust 36 116231-0069 is precisely 20 millimetres. This specification is critical for strap compatibility: any aftermarket or vintage strap must have a 20mm width to fit correctly between the case lugs without gaps or overlaps.

What is the best strap for the Rolex Datejust 36 116231-0069?

For a two-tone Datejust 36 in rose gold and steel, we recommend straps in alligator or shell cordovan dyed chocolate brown, black, or cognac. Alligator delivers consistent grain texture that highlights the case polish, whilst cordovan develops an organic patina over time. Both materials, when vegetable-tanned, age beautifully.

How do I change the strap on the Rolex Datejust 36 116231-0069?

Strap removal requires extracting the spring bars from the case lugs using a dedicated tool. Position the watch on a soft pad, insert the spring bar tip into the lug hole and press downward gently: once released, the old strap detaches. Thread the new strap by aligning the spring bars to the lugs and allow the spring to seat. If unfamiliar with this procedure, consult a certified watchmaker.

Is an aftermarket strap compatible with the Rolex Datejust 36 116231-0069?

Yes, provided the lug width is 20mm. High-quality aftermarket straps, such as those handcrafted by Casati Milano, are entirely compatible and frequently offer superior leather finishes and craftsmanship compared to Rolex alternatives. Always verify that the ansa aligns with the case lugs before purchase.

How long does a leather strap last on the Rolex Datejust 36 116231-0069?

Strap longevity depends on material type and wear frequency. An alligator or shell cordovan strap treated with vegetable tanning, worn 5–6 days weekly, maintains structural integrity for 5–7 years. The leather develops a rich, personalised patina naturally. With proper maintenance (avoid prolonged moisture exposure, apply leather conditioners), the strap ages gracefully alongside the watch.
