Strap for D-Star Ceramos Automatic

The Rado Oval R15947103 features a lug width of 20mm. This measurement is standardised for the model and allows for easy pairing with compatible artisanal straps from specialised retailers. To verify the measurement, use a calliper or ruler to measure the distance between the inner edges of the lugs on your watch.

The Rado Oval R15947103 achieves maximum aesthetic potential when paired with alligator or vegetable-tanned calf leather straps. These materials amplify the sculptural geometry of the case and the natural patina of the Cermet. Alternatively, high-quality NATO fabric straps and technical rubber straps represent robust and versatile options for sporty and everyday contexts.

Strap replacement requires a specialised spring bar tool or, alternatively, professional watchmaker assistance. Insert the tool beneath the metal pin connecting the strap to the case, applying gentle upward pressure to release the internal spring. Repeat from the opposite side, then align the new strap holes with the lugs and press until the spring bar clicks into place.

Yes. Since the Rado Oval R15947103 utilises the standard 20mm lug width, you can purchase aftermarket artisanal straps from specialist watchmaking laboratories. Milano Straps offers a dedicated catalogue of 20mm straps in natural leather, technical fabrics and rubber, all tested for compatibility and superior construction quality to OEM alternatives.

Leather strap longevity depends on usage intensity, moisture exposure and mechanical wear. Under moderate use and routine maintenance—periodic cleaning and drying after water exposure—a high-quality strap in alligator or vegetable-tanned calf leather maintains structural and aesthetic integrity for 18–24 months. Technical rubber straps offer greater durability, lasting 3–4 years without significant loss of physical properties.
