Datejust 36 116243-0023— lug 20mm

The Rolex Datejust 36 116243-0023 is equipped with 20-millimetre lugs. This dimension is specific to this model and must be observed precisely when purchasing a compatible strap. 19mm or 22mm straps will not fit correctly, causing excessive movement or inability to seat in the case pins.

The ideal strap depends on intended use. For formal contexts, a dark brown alligator or vegetable-tanned calfskin box strap enhances the two-tone gold and steel aesthetic. For daily wear, polished shell cordovan or cognac-toned calfskin creates visual balance. Those seeking versatility opt for a two-tone calfskin and canvas strap, or a resilient canvas NATO.

Strap replacement requires two tools: a flathead screwdriver (or dedicated tool) and gentle outward pressure. Position the watch with the lug facing you, insert the tool into the pin groove and press gently outward until the metal axis fully retracts. Repeat on the opposite side. Insert the pins into the new strap and seat the first axis, then the second. If inexperienced, consult a certified watchmaker.

Yes, provided the lug width is precisely 20mm. Quality aftermarket straps, such as those crafted in alligator or calfskin, seat into original Rolex pins without modification. Many collectors favour custom straps from specialised ateliers because they allow complete personalisation—from material to buckle finish.

Longevity depends on material and use. Vegetable-tanned alligator lasts 4–6 years with daily wear, developing natural patina. Box calfskin may reach 5–7 years. Shell cordovan, owing to structural density, lasts 6–8 years. These periods extend significantly if the watch is worn intermittently or rotated with other straps. Artisanal quality and natural tanning always guarantee superior longevity compared to industrial straps.
