Frequently asked questions
What is the lug width of the Rolex Datejust 36 126233?
The Rolex Datejust 36 reference 126233 features 20-millimetre lugs. This measurement represents the space between the two lugs on the case where the strap inserts. To verify, remove the strap from the lugs and measure the width of the metal end: you will find 20mm. This is a critical measurement when replacing the strap.
What is the best strap for a Rolex Datejust 36 126233?
There is no single 'best' strap in absolute terms, only the most suitable for your intended use and personal preference. For classical elegance, a brown or burgundy alligator creates the finest contrast with the Rolesor case. For maximum formality, glossy black calf leather is unmatched. If you seek daily versatility and durability, shell cordovan in vegetable tanning ages extraordinarily well and develops a unique patina. For sporting use, a high-density rubber strap remains the most practical choice.
How do I change the strap on a Rolex Datejust 36?
Strap replacement requires a spring bar tool (a small bifurcated instrument). Position yourself on one side of the case, locate the tiny hole in the lug, insert the tool's tip into the opening to compress the internal spring, and the strap releases. Repeat from the opposite side. When installing the new strap, ensure that the 20mm lugs sit completely within the case lugs with no lateral gaps. If you are uncertain about the procedure, consult a specialist.
Is an aftermarket strap compatible with the Rolex Datejust 36 126233?
Yes, provided it is constructed with 20-millimetre lugs. The Datejust 36 does not employ proprietary Rolex lugs, so any quality artisanal strap with the correct measurement fits perfectly. Always verify that the maker specifies '20mm' in the technical specifications. Straps crafted by specialised ateliers such as Casati Milano guarantee impeccable fit and construction befitting the case.
How long does a leather strap last on a Rolex Datejust 36?
Longevity depends on material and usage patterns. Quality alligator or shell cordovan typically lasts 5–8 years in intensive daily use, longer if rotated amongst multiple straps. Vegetable-tanned leather ages rather than wears out, developing character and patina. High-density rubber maintains structural integrity beyond 10 years if not exposed to prolonged direct heat. With Casati Milano, every strap is guaranteed against manufacturing defects for 18 months. Periodic maintenance—cleaning with neutral soap and air-drying—significantly extends useful life.
