Viewing Distances

25m – (75ft)

Please note that we base our suggested maximum viewing distances on users with average eyesight working in typical ambient lighting conditions.

Users with below-average vision may experience problems at the maximum quoted ranges or under bright lighting.

Please also be aware that blue illuminated characters can appear slightly out of focus to some people due to variations in the response of the human eye to blue light.

Clocks with blue digits typically have a shorter maximum viewing distance for many people than red, green or yellow/amber characters.
