The new Phosphor World Time Sport uses an E-ink display in its face, which isn’t something new, however this watch is quite sleek. It’s also waterproof and since the display doesn’t use much power, you won’t have to change the battery anytime soon.
These modern digital watches don’t use LED or LCD screens. Instead, they use E-Ink screens to tell the time.
Phosphor’s E-Ink watches have a bold modern design, and feature highly readable electrostatic displays.
The Phosphor DH01, DH02 and DH03 all feature a display that combines a dramatic modern numeric display for minutes, along with a simulated analog dial for the current hour.
