Frequently asked questions

What is the lug width of the Rolex Datejust 36 116234-0120?

The lug width of the Rolex Datejust 36 116234-0120 is precisely 20 millimetres. This measurement is taken between the case lugs (the horizontal attachments on either side of the watch case). Accuracy is essential to ensure compatibility with any aftermarket strap.

What is the best strap for the two-tone Datejust 36?

The optimal choice depends on intended use. For formal occasions, dark brown alligator or shell cordovan deliver maximum sophistication and visual harmony with the two-tone case. For daily wear, vegetable-tanned calfskin in black offers elegance with practicality. For those seeking sporty versatility, an FKM rubber strap in charcoal grey combines durability with modern refinement.

How do I change the strap on the Datejust 116234-0120?

You will need a dedicated spring bar remover tool. Position the watch on a soft cloth, locate the spring bars (the horizontal pins at each ansa extremity), apply gentle lateral pressure to flex the bar and release it from its seat. Repeat on the opposite side. Install the new strap by reversing the procedure: insert the bars into their respective seats and confirm they seat securely.

Is an aftermarket strap compatible with the Rolex Datejust 36?

Yes, provided the lug width is exactly 20mm and the strap has been manufactured with precision tolerances. High-quality artisanal straps – in alligatore, shell cordovan, or calfskin – are not only compatible but add personality and uniqueness to the Datejust, as each develops its own patina and character over time. We recommend specialised manufacturers who guarantee rigorous millimetric tolerances.

How long does a leather strap last on a Rolex Datejust?

A high-grade leather strap (alligator, shell cordovan, vegetable-tanned calfskin) with daily wear typically lasts 3–5 years before showing significant signs of fatigue at the flex point. Climate, perspiration, and frequency of wear influence longevity considerably. Periodic maintenance – quick drying if wetted, occasional application of leather conditioner – substantially extends strap lifespan and deepens the visual patina.
