A. After looking into this issue we can assure that the materials used on our models are generally stainless steel and resin which do not contain any toxic substance. However, the following factors may be contributing to the skin problem you are experiencing.
Firstly, over time any watch may be subjected to small amounts of sweat, dirt or naturally forming bacteria on the resin band. This may in some cases cause a reaction such as this and we would advise to clean the watch thoroughly and wait for the inflammation to subside before trying the watch again under close supervision.
Alternatively whilst the watch does not contain any toxic substances you may be experiencing a particular metallic allergy. If the problem persists or worsens we would advise seeking medical advice.
As stated above there are no harmful toxins contained within any of our products.
