In the 1970's, YEMA launched its first iconic LED display watches. Nowadays, LED displays contribute to the retro vibe while allowing to read time in style, LED displays remain in standby mode and only light up when activating the LED quartz module by pushing the side button.

This push-button operation experience that activates the LED display is part of the pleasure in owning and using one, adding another layer of charm to the watch. Upon activation, the LED display illumination length is as follows:

- YEMA LED classic models: 2-3 seconds

- YEMA LED Kavinsky: 8-9 seconds

The display uses LED technology while the movement uses classic quartz architecture, offering a daily accuracy of +2 seconds.

YEMA LED Caliber main functions are: Hour, minutes (12h/24h), seconds, date, month, year.

Battery lifespan differs greatly depending on its usage: 2 years (intensive usage) to 4 years (occasional usage).
