Strap for Datejust 36 Rolesor Yellow Diamond / Jubilee / Black Computer Roman

The bicolour Datejust 36 reference 116243-0014 is fitted with 20-millimetre lugs. This measurement is Rolex's design parameter that balances the proportions of the 36mm case. Always verify compatibility by measuring the distance between the case lugs before purchasing an aftermarket strap.

For this bicolour model with champagne dial, natural alligator remains the classical choice: its regular grain coordinates seamlessly with precious metals. Brown-taupe or cognac alligator amplifies the warmth of yellow gold; pure black emphasises formality. For those seeking artisanal character, vegetable-tanned calf or shell cordovan in reddish-brown offer textural evolution over time.

The strap is removed via the spring bars that pass through the case lugs. Use a dedicated spring bar tool to push the bars from the sides and facilitate extraction. The procedure requires care to avoid scratching the case sides. If inexperienced, consult a trusted watchmaker or Casati Milano's strap change service.

Yes, provided the strap is sized at 20 millimetres lug width. High-quality artisanal straps in alligator, calf, or shell cordovan are fully compatible with this case. Verify that the spring bars (or supply your own) have the correct diameter to engage with the Rolex case lugs.

Longevity depends on material and usage. Quality alligator resists 4–6 years with routine maintenance and moderate daily wear. Shell cordovan, due to superior fibre density, reaches 6–8 years. Vegetable-tanned calf varies between 3–5 years depending on UV exposure and humidity. Casati Milano's artisanal straps include an 18-month warranty on manufacturing defects; subsequent longevity depends on maintenance and wearing habit.
