The Minox Suntimer UV Alarm Watch.

This puppy provides a little bit more intelligence than your average UV monitor, since it calculates your optimum UV exposure based on a number of factors which you enter, such as skin type and the sunscreen you’re using. This is clearly a product for those who spend long hours in the sun. It costs €49.00.

With its special sensors it measures the amount of ultraviolet radiation in the sunlight and provides you with information on its intensity. To determine an optimum time to stay in the sun, important individual factors can be programmed into this tiny instrument, such as skin type and the protection factor of sunscreen in use. In this way, the user gets a maximum time reading which is individually adjusted to his or her personal profile, and when that time expires the Suntimer sounds an alarm to suggest you get out of the sun.
