For routine care, wipe a ceramic watch with a soft microfiber cloth. Rado also recommends cleaning with soap water, but that is Rado’s guidance—not a guarantee that every ceramic watch can be rinsed or submerged. Before using water, check the watch’s manual and water-resistance instructions. Ceramic resists everyday scratches, but it can still be scratched by abrasive or very hard materials and can break if dropped.
How to clean the case and bracelet
Routine wipe-down
Use a clean, soft microfiber cloth to remove fingerprints and everyday surface dirt. Rado recommends a microfiber cloth for regular cleaning; its FAQ also lists soap water as an option. Those recommendations are specific to Rado, so follow your own watchmaker’s instructions for water-based cleaning.

When using water
Do not assume a ceramic case makes a watch safe to rinse or immerse. Water resistance depends on the particular watch, its condition, and its construction. Check the manual before using anything beyond a dry or lightly damp cloth, and do not expose the watch to water if its instructions do not permit it. Longines, for example, provides care instructions by watch name, reference, or calibre, reflecting the need for model-specific guidance: Longines watch care instructions.
Care for the strap according to its material
The case and strap may need different treatment. Citizen’s general watch-care guidance distinguishes among metal, leather, and rubber or silicone straps. It is not ceramic-specific, and your watchmaker’s manual takes precedence.

- Metal bracelet: Citizen advises using a soft brush and warm soapy water while avoiding the watch case. Only use this water-based method if your watch’s instructions and water-resistance rating allow it.
- Leather strap: Citizen advises wiping leather with a soft, dry cloth. If it gets wet, allow it to dry.
- Rubber or silicone strap: Citizen says these straps may be cleaned with mild detergent and water, then rinsed and dried. Confirm that the watch’s instructions permit water exposure before cleaning a strap while it is attached.
See Citizen’s general watch-care guidance for its material-specific recommendations.
Prevent scratches and breakage
“Scratch-resistant” does not mean scratch-proof. Rado describes high-tech ceramic as capable of withstanding scratching from normal everyday use, but warns that hard materials or particles can still scratch it. Its examples include sand, granite, and nail files. Keep the watch away from abrasive grit and hard surfaces, and avoid storing it where it can rub against such materials.

Ceramic can also break if the watch is dropped. Handle it carefully and avoid impacts; resistance to ordinary surface scratching does not make the case unbreakable. Rado’s explanations of ceramic care and scratch resistance are in its Master of Material FAQ.

Routine exterior wiping is different from repairing damage or opening the watch. If the case or bracelet is chipped or cracked, or the watch needs a battery replacement or other work beyond gentle exterior cleaning, contact the manufacturer’s authorized service network. For Rado watches, Rado recommends an authorized service centre for battery replacement and says spare parts are sold only to authorized service partners; see its US customer-service FAQ.

What the ceramic hardness figure does—and does not—tell you
Rado gives an approximate hardness of 1,250 Vickers for its high-tech ceramic. That figure is Rado’s stated value, with no year specified on the FAQ page; it is not a universal hardness rating for every ceramic formulation or a promise that a watch cannot be scratched or broken. The same FAQ gives a separate figure for Ceramos, a distinct Rado material, which should not be treated as the hardness of ceramic watches generally.
