Strap for Datejust 36 Stainless Steel / Fluted / Pink Roman-Diamonds / Jubilee

The lug width of the Rolex Datejust 36 126234-0031 is 20 millimetres. This measurement represents the exact distance between the lugs of the case where the strap connects. It is essential to verify this dimension before purchasing an aftermarket strap, as any different width – 18 millimetres or 22 millimetres – will not fit correctly and may damage the case.

For a Datejust 36 in two-tone white gold and steel, alligator is the most natural and sophisticated choice: its fine grain, cool colour and ability to age nobly make it ideal for a dress watch. Shell cordovan excels for those preferring density and accelerated patina development. Vegetable-tanned calf offers contemporary accessibility, whilst Cordura NATO in canvas proves effective for sporty-elegant use without weighing down the 36mm proportion.

Changing the strap on the Datejust 36 requires a dedicated tool (spring bar tool) and careful attention to avoid scratching the case. Gently remove the original strap by extracting the elastic pin (spring bar) from one side to the other. Insert the new strap by aligning the holes with the lugs, then reinsert the pin with even pressure. If you are inexperienced, we recommend entrusting this to a skilled watchmaker: poor execution can compromise the case and water-resistance of the watch.

Yes, you can fit an aftermarket strap provided it respects the 20 millimetre lug width. Choose recognised quality manufacturers that guarantee premium materials (alligator, shell cordovan, vegetable-tanned calf) and precise construction. An artisanal strap from master leatherworkers ensures durability, ennobling patina over time and superior tactile comfort compared to industrial straps. We recommend verifying certifications and brand history before purchase.

The lifespan of a leather strap depends on the material, daily use and maintenance. Quality alligator lasts on average 3-5 years with moderate wear. Shell cordovan, being denser, can exceed 6-7 years. Vegetable-tanned calf has lower resistance, around 2-3 years with daily use. Regular maintenance – cleaning with a soft cloth, protection from excessive sweat and moisture, drying after water contact – significantly extends strap life.
