The Seawatch UV Master is a unique watch with UV sensor has been developed in order to help you to protect your eyes and skin from UV radiation.

With the ever increasing worries about skin cancer and cataracts from our changing climate this watch provides the wearer with a simple warning system to the potential of sunburn. A UV sensor located on the front of the watch takes a reading every ten seconds and displays a UV index number, as well as a simple bar graph on the LCD screen to give a visual indication of the UV index.

To create a further level of protection the UV Master is fitted with 2 user adjustable alarms; these sound when the UV radiation reaches the levels set by the wearer. All this is built into a normal wristwatch that has all the usual functions such as current time mode, daily alarm mode, chronograph mode and timer mode.

The Global Solar UV Index (UVI)

The UVI is a simple measure of the UV radiation level at the Earth's surface. It has been designed to indicate the potential for adverse health effects and to encourage people to protect themselves. The values of the Index range from zero upward and the higher the Index value, the greater the potential for damage to the skin and eye, and the less time it takes for harm to occur.

Everyone is exposed to ultraviolet (UV) radiation from the sun. Small amounts of UV radiation are beneficial to people, and play an essential role in the production of vitamin D. However, overexposure to UV radiation is responsible for two major public health problems: skin cancer and cataract.
