Frequently asked questions

What is the lug width of the Rolex Datejust 36 Ref. 126201-0015?

The lug width is 20 millimetres. This measurement is calculated from the inner wall of one lug to the inner wall of the opposite lug. To verify your strap's conformity, measure the space with a ruler positioned perpendicularly to the lugs. Rolex's manufacturing tolerance is ±0.1 mm, therefore quality professional aftermarket straps must respect this standard to ensure precise assembly without forced fitting.

Which strap would you recommend for the Datejust 36 126201-0015 two-tone model?

For the Everose and steel configuration, we recommend cognac or dark brown alligator, which enhances the warmth of rose gold. Alternatively, vegetable-tanned calf in black accentuates the two-tone's contemporary nature, or Bordeaux shell cordovan creates a sophisticated visual dialogue. Avoid cool tones (blue, grey) that diminish the case's luminosity.

How do you change the strap on a Rolex Datejust 36?

The procedure requires a specific tool called a spring bar remover. Position the watch with the upper lug facing towards you, insert the tool's tip into the small hole between lug and passant, applying downward pressure to compress the internal spring. The metal tip retracts, freeing the spring terminus. Repeat from the opposite side. For reassembly, align the passants to the lugs and press until the locking click is felt.

Is an aftermarket strap compatible with the Datejust 36 126201-0015?

Yes, provided the lug width is precisely 20 mm. Quality artisanal straps—in alligator, vegetable-tanned calf, shell cordovan—are entirely compatible without mechanical modifications. The Rolex case is engineered to accommodate standard manufacturing tolerances, therefore you need only select material and colour according to your aesthetic preferences.

How long does a leather strap last on a Datejust 36?

Durability depends on usage and maintenance. Quality alligator, with proper care (monthly cleaning with damp cloth, half-yearly conditioning), maintains full functionality for 5-7 years. Vegetable-tanned calf, softer initially, resists 3-5 years under intensive wear. Shell cordovan, although more robust, develops visible creasing after 4-6 years. To extend longevity, alternate straps to avoid overloading a single solution.
