Datejust 36 116244-0060— lug 20mm

The lug width (ansa width) of the Rolex Datejust 36 116244-0060 is 20 millimetres. This measurement is specific to this model and determines which strap can properly fit into the lateral supports of the case. A 18mm or 22mm strap will not be compatible. To verify, measure the distance between the two attachment holes: it must be exactly 20mm.

The best strap depends on your intended use. For formal contexts, alligator leather with vegetable tanning represents the most recommended choice due to its fine grain and texture that does not compete with the white gold case. For elevated daily wear, calf leather with a maturing patina offers softness and lasting elegance. For versatility, an FKM rubber strap or silk synthetic NATO ensures practicality whilst maintaining dignity. Your choice should be coherent with the tone of the wrist that wears it.

To change the strap, you will need a spring bar removal tool. Locate the two holes on the underside of the case where the current strap connects. Insert the tool into the hole to push the spring bar inward, then extract the old strap. Align the holes of the new strap (20mm lug width) with the case holes and press the spring bar until it clicks into position. Verify that the strap is firmly secured before wearing the watch.

Yes, any aftermarket strap with a 20mm lug width is compatible with the Rolex Datejust 36 116244-0060, provided that the spring bars are the correct size (typically 18mm in length for this model). High-quality artisanal straps often offer advantages over original Rolex straps: greater colour personalisation, exceptional materials such as vegetable-tanned alligator or shell cordovan, and more accessible pricing. Ensure the strap has been made specifically for the 20mm measurement to avoid slipping on the case.

The lifespan of a leather strap varies based on material and intensity of use. Quality alligator or calf leather worked with vegetable tanning lasts an average of 3-5 years with moderate daily wear. Shell cordovan, thanks to its natural density, can exceed 7 years. Leather requires maintenance: avoid prolonged water immersion, dry quickly if exposed to moisture, and occasionally apply a specific conditioner. An FKM rubber strap offers superior durability (up to 10 years) with resistance to salt water and chlorine, ideal for marine environments. Periodic replacement is not a defect: it is the natural ageing of a living material.
