Rado
Oval R15965159— lug 18mm

The lug width of the Rado Oval R15965159 is 18 mm. This specific measurement is determined by the elliptical case geometry and requires straps designed precisely for this dimension. To verify correctly, position a calliper between the two lugs on the top of the watch: the internal distance must be exactly 18 mm.

For the Rado Oval R15965159, the most recommended straps are: alligator or vegetable-tanned calf leather for formal elegance and developing patina over time; NATO canvas for casual versatility; quality rubber for sporting or water-based use. The choice depends on daily wear and the role you assign to the watch.

To change the strap, position the watch with the case facing upwards. Locate the spring bars at the ends of each lug. Use a dedicated tool (spring bar tool) to press the bar inward, releasing the end of the previous strap. Repeat on the other side. Insert the new 18 mm strap by aligning it perfectly with the lug and release the spring bar.

Yes, any strap with an 18 mm lug width is compatible with the Rado Oval R15965159, provided it is manufactured to adequate quality standards. Artisanal 18 mm straps available online guarantee perfect fit to the lugs without lateral gaps or excessive tension, maintaining the original aesthetic balance of the case.

Durability depends on leather quality and usage. An alligator or vegetable-tanned calf strap can last 5-10 years with ordinary care (gentle cleaning, avoid prolonged intense sunlight). Rubber straps have shorter lifespan (2-4 years) but tolerate humid environments better. Natural patina and minor wear marks are normal and increase aesthetic appeal over time.
