Hi, I wonder if the watch turns gray after some time or is there any way to prevent it. Let's say buy some liquid to clean it. Thank you for answer.

- Hello, Thank you for your inquiry. Pewter (English tin) will remain shiny if you keep it away from heat and harsh chemicals. That is why you should wear this watch during intense physical activities such as exercise, cleaning the house, washing dishes, etc. Pewter is also soft metal, which can easily bend. Use a sponge or soft brush for cleaning. Takak the sponge in lukewarm clear water, normally wipe the watch and allow it to dry at room temperature (no heating, etc.). The watch does not need any extra maintenance. And if so, please consult a watchmaker as an expert.

Please flashlight is changeable?

- Yes.
