Frequently asked questions

What is the lug width of the Rolex Datejust 36 126201-0032?

The lug width (ansa width) of the Rolex Datejust 36 126201-0032 is precisely 20 millimetres. This dimension is the distance between the case lugs and accommodates straps and bracelets specifically sized for this measurement. The lug depth is approximately 4.5 mm, suitable for leather thicknesses ranging from 1.8 to 2.8 mm.

Which strap would you recommend for the two-tone Datejust 36 in rose gold and steel?

For the Datejust 36 126201-0032, we recommend vegetable-tanned alligator in cognac, brown, or blue tones to enhance the rose gold, or vegetable-tanned calf in brown or navy blue for a cooler aesthetic. Shell cordovan is ideal if you desire a leather that develops patina over time. Avoid NATO straps: their inherently sporty character contradicts the formal essence of this model.

How do I change the strap on my Datejust 36?

Strap replacement requires a specialist tool (spring bar tool) and delicate handling. Position the watch with the caseback facing upward, locate the small holes in the case lugs, insert the spring bar tool to compress the internal spring and slide out the old strap. Replace with the new 20 mm model and verify correct closure. If uncertain, consult a professional: mishandling could compromise the case.

Does using an aftermarket strap void my Rolex warranty?

No, legally. International regulation (Directive 2006/42/EC) permits the use of aftermarket straps on warranty watches, provided they are of equivalent structural quality (correct lug width and suitable material). However, Rolex may dispute defect claims if the strap is deemed the cause of damage. For this reason, we recommend retaining the original Oyster bracelet and selecting specialised makers such as Casati Milano.

What is the expected lifespan of a leather strap for a Datejust 36?

A high-quality artisanal strap in alligator or calf, subject to routine maintenance (monthly cleaning, drying after humidity exposure), lasts 3–5 years with daily wear. Shell cordovan, owing to its superior fibre density, can reach 6–7 years. Longevity depends on exposure to humidity, heat, direct sunlight, and usage frequency. Lower-quality straps last 18–24 months. We provide an 18-month guarantee against manufacturing defects.
