Strap for Day-Date 36 Yellow Gold / Strap / Green

The lug width of the Rolex Day-Date 36 reference 118138-0030 is 20 millimetres. This measurement is determined by the distance between the two lugs that support the strap on the case. It is essential to verify this specification before purchasing an aftermarket strap to ensure perfect compatibility and avoid play or excessive pressure on the case.

For the Day-Date 36 in yellow gold, straps in alligator with vegetable tanning, Tuscan calf, or shell cordovan are recommended. These materials offer durability exceeding ten years and develop a natural patina that enhances the warmth of yellow gold. An alligatore strap in brown or tobacco creates harmonious colour matching and maintains the classic character of the presidential model.

Changing the strap requires extraction of the spring bars that support the lugs on the case. Use a dedicated tool (spring bar removal tool) to release the tension of the internal spring, then extract carefully from one side. Repeat the operation on the other side. The new strap is fitted by positioning the first spring bar, then the strap, and finally the second spring bar. Extraction and reinsertion must be performed with extreme care to avoid damage to the case.

Yes, provided the strap presents the correct 20 mm lug width. Artisanal leather straps from specialised ateliers guarantee construction compatibility and superior quality compared to standard straps. It is important to verify that the supplier clearly specifies the lug width and offers a warranty on construction.

The lifespan of a high-quality leather strap ranges between 7 and 15 years depending on usage, climatic conditions, and care. Vegetable-tanned leather tends to last longer than chrome-tanned leather. A shell cordovan or superior-grade alligator strap can last beyond twenty years. Regular maintenance—gentle cleaning, moderate conditioning—significantly extends longevity.
