— the backlight allows you to see the clock in low light conditions — up to complete darkness. It can be done in different ways, depending on the type of dial. So, in purely analogue watches, either a luminescent coating on the hands (and often on the scale divisions) or tritium elements installed in the same place is usually used. The first option is simpler and cheaper, but such illumination in the dark does not work for long (several hours) and requires regular “charging” from bright light; the second option is noticeably more expensive, but does not depend on external light, and the service life has been measured for years. Clocks with a display are usually illuminated by miniature light bulbs powered by the clock battery; Of course, such a backlight does not work constantly and turns on for a short time at the touch of a button.| clear | Save List |
