hat would be the best way to clean your watch? The team at AIS Collective, a Swiss startup, tried different products, from a simple toothbrush to multi-product solutions. Their conclusion was that none of these options seemed to be appropriate in terms of safety and user experience. And the risks were numerous: scratching the case, drying out seals, building up residues or abrading parts of the watch…

From a technical perspective, there are two main approaches to cleaning your watch: physical and chemical. AIS Collective has developed the ChronoPen, which is specifically designed to gently yet thoroughly clean your watch, no matter what metal it’s made of. It is also a great tool to clean your metal bracelet, rubber strap and caseback. The brush of the ChronoPen comes with extra soft and extra long bristles so you can reach every nook and cranny and really remove the grime from between the links of your watch’s bracelet.

The Swiss-made cleaning agent inside the ChronoPen is designed to be gentle on all metals and common watch case materials. This means that the liquid is non-alcoholic, non-abrasive and also contains no oils or other substances that may build up residue. Just like the brush, the liquid inside the ChronoPen is designed to remove dirt and grime carefully, yet effectively.
