The ChronoPen has been tested to reach even the most intricate of watches from case to bracelet to lug interior and the solution does not contain any aggressive chemicals or abrasives. It is ideal for stainless steel, gold, platinum, bronze, carbon fibre, ceramic as well as other external parts of a watch including sapphire crystal, diamonds and rubber/ silicone.
An AIS Collective dual-purpose towel is included with each order. This natural cotton, extra thick, 30cm × 30cm towel can be used for both drying (white side) and polishing (black side).
Each brush contains enough cleaning solution for up to 60 uses.
NOTE:
Please check the water resistance rating of your watch before use; don't use the ChronoPen on any watch that isn't tested to withstand water ingress. Leather straps should always be removed before using the ChronoPen.
