Engraving is carried out using laser technology. As a result, the colour of the engraving may differ from this illustration depending on the material and condition of the product.
The embossing is applied to the leather straps by means of stamps. Please note that the embossing differs in colour and texture from the illustration. Limited to max. 3 characters, you can emboss your strap with letters from A to Z, numbers from 0 to 9 and the symbols "." and ",".
Please note that Rado reserves the right to refuse to add personalisations that are obscene or offensive.
Engraved watches, watch bracelets that are sized (cut) and embossed straps are considered final sale and are not eligible for returns or exchanges.
