Phosphor has taken time telling to new heights with the introduction of the World Time E-Ink watches. Well, these are among the first (or are they the only) watches on this blue planet that brags about being E-Inked and makes it available for an affordable price. Of course these show you which one’s a better pick between them and Sieko’s offerings.

There are a total of four of these cool time tellers. These are water resistant to 50 meters.
It is available as a stainless steel version, black or white rubber or black leather. The steel version is the most expensive of the lot.
