The Swiss Made ChronoPen is designed to be simple in use but thorough in cleaning.

Here are the five simple steps:  

1. Check your watch is water-resistant and the crown is wound down fully. Further, remove leather straps. Metal bracelets and rubber straps are safe to be cleaned with the ChronoPen.  


2. Hold the ChronoPen upwards, take off the lid and pump the button a few times brush facing upwards, until foam is coming out.  

3. Start moving our specially designed soft brush in a circular motion across all parts of your watch.


4. Rinse the watch under clean, lukewarm water and dry the watch with a clean and dry cotton towel.  

5. Rinse the brush of the ChronoPen under running water.
