Clean a Rado Captain Cook gently: use a microfiber cloth for dust and fingerprints, or lukewarm, slightly soapy water and a toothbrush for a more thorough clean. Rado recommends cleaning after contact with salt water or cosmetics. Ceramic resists everyday scratches, but it can still be scratched or broken, so avoid hard impacts and abrasive materials. Before using water, consider the condition of your particular watch’s water resistance.
Identify which parts of your Captain Cook are ceramic
Captain Cook materials vary by reference. Some Rado listings show a High-Tech Ceramic bracelet, while other models pair a ceramic bezel component with a stainless-steel bracelet. Check the reference number and its product information or documentation before treating the whole bracelet as ceramic.

This distinction matters when cleaning: follow the guidance for the actual watch, and do not assume every Captain Cook has the same construction or water-resistance rating.

For a more thorough clean
Rado’s maintenance manual recommends lukewarm, slightly soapy water and a toothbrush for occasional cleaning, particularly after contact with salt water or cosmetics. Use this wet-cleaning method only if it is appropriate for your watch’s current water-resistance condition and its instructions. Rado cautions that water resistance is not permanent.
The official guidance supports these gentle methods; it does not establish immersion, ultrasonic cleaning, polishing compounds, abrasive pads, or chemical cleaners as safe for the Captain Cook’s ceramic parts.

What can scratch or break ceramic?
High-Tech Ceramic is scratch-resistant in normal everyday use, but it is not scratch-proof or unbreakable. Rado says materials as hard as or harder than ceramic can scratch it, naming nail files, granite, and sand as examples. Sand can be especially relevant when it is trapped against the watch or bracelet during handling.
Rado gives an approximate hardness of 1,250 Vickers for High-Tech Ceramic. That figure describes material hardness; it does not mean the watch cannot be scratched or damaged by an impact. Rado also warns that a dropped watch may break. Avoid knocks, shocks, and drops, and keep the ceramic away from hard surfaces and particles that could rub against it.

When to contact Rado service
If the watch has been dropped, struck, or otherwise damaged, or if it needs maintenance, contact an official Rado dealer or service centre. Rado recommends authorized checks because water resistance can diminish over time; do not rely on an old rating as proof that wet cleaning is safe today. Its service FAQ also states that spare parts are sold exclusively to authorized service partners.
