Strap for D-Star

The Rado Oval R15517152 features an 18-millimetre lug width. This measurement represents the internal space between the two lugs of the case and directly determines the compatible strap width. To verify the measurement accurately, use a digital caliper positioned perpendicularly to the lug, measuring from the inner edge of one lug to the other. A tolerance of ±0.5 millimetres is considered normal in watchmaking.

Strap selection depends on your personal style and context of use. For a classical approach, we recommend alligator leather with vegetable tanning in brown or black tones, which amplifies the modernity of the ceramic case. For immediate comfort, vegetable-tanned calf offers softness and fine grain. For versatility, a cotton NATO allows rapid changes. For those seeking continuity with Rado's technological philosophy, a moulded rubber strap guarantees water resistance and UV durability. All straps must feature an 18-millimetre lug width.

Strap replacement requires precision and care. Position the watch on a soft surface with the case facing downward. Use a spring bar tool to gently depress the internal springs of the lugs. Remove the old straps carefully, then insert the new ones, ensuring the springs lock completely on both sides. Verify secure fastening before wearing the watch. If you lack experience, we recommend consulting a professional watchmaker to avoid damage to the case.

Yes, you can mount an aftermarket strap of quality construction on a Rado Oval R15517152, provided it features precisely an 18-millimetre lug width. Artisanal leather straps, particularly those with vegetable tanning, offer construction quality that can equal or exceed Rado's standard offerings. A well-crafted aftermarket strap provides deeper personalisation than standard Rado options, allowing you to adapt your watch to your aesthetic and tactile preferences.

Leather strap longevity varies significantly depending on material quality, tanning method, and your lifestyle. An alligator or premium calf strap with vegetable tanning can last 3-5 years with regular maintenance and rotation with other straps. A cotton NATO typically resists 2-3 years before the weave begins to fray. A rubber strap generally lasts 4-7 years. Prolonged sun exposure, moisture, and chemical agents accelerate ageing. Regularly conditioning the leather with specialist creams and rotating straps extends their lifespan considerably.
