Strap for Datejust 36 Rolesor Everose Fluted / Oyster / White Diamonds

The lug width of the Rolex Datejust 36 reference 116231-0063 is precisely 20 mm. This measurement represents the distance between the two attachment points of the strap on the case. To verify accurately, measure from the inner base of the left lug to the inner base of the right lug, passing through the bottom of the case. All compatible straps must have a lug width of exactly 20 mm.

For this two-tone configuration, African alligator represents the most sophisticated choice: its natural parallel grain creates an elegant dialogue with the brushed surfaces of the steel and rose gold case. A deep brown or tobacco colour amplifies the warmth of the gold without competing visually with the case. Alternatively, Japanese shell cordovan offers pronounced texture and fascinating natural ageing. For sportier contexts, a silk NATO or FKM rubber with stainless steel deployante are functional choices.

Strap replacement requires a specific tool: a strap changer (or spring bar removal tool). Position the watch with the lugs facing upwards, locate the small groove between the lug and case, insert the flat blade of the tool and push downwards until the retaining pin is released. Repeat on the opposite lug. To insert the new strap, align the holes and push the pin inwards until you feel the click of secure placement. If you are unfamiliar with the procedure, consult a certified watchmaker.

Yes, any aftermarket strap with a 20 mm lug width is compatible with the 116231-0063. Compatibility depends solely on this dimension, not on the specific reference of the watch. However, it is essential to choose a quality strap: the leather must have appropriate thickness (1.4–1.6 mm) to avoid altering the visual proportions of the case, and the leather keeper must allow the strap to follow the natural curve of the wrist.

The lifespan of a leather strap depends on the material, tanning method and intensity of use. African alligator with vegetable tanning lasts on average 4–6 years with daily wear; Japanese shell cordovan resists 5–7 years due to structural density; vegetable-tanned calf leather ages naturally and remains wearable beyond 8 years, developing a fascinating patina. Factors such as humidity, perspiration and sun exposure accelerate wear. Periodic maintenance (gentle cleaning, leather balm) significantly extends the useful life.
