Nauticalia

This alarm clock receives a time signal from the atomic clock at Anthorn, Cumbria, so it is far more accurate than any traditional desk clock. It has automatic set-up, regular time checks, and even self-adjustment for summer/winter time.

Includes a snooze function and light. Takes 1 AA battery (option to purchase will appear in your shopping basket).
Measures 4¼" x 4".
