The Wena Wrist is a smart watch that offers notifications through vibrations and a small LED light on the band, wallet payment compatible with the Japan-only Felica standard, and can go for as long as a week between charges. The watch itself is a typical analogue watch (available with a chronograph face) and so it can go on for much longer. The wena wrist charges through its own proprietary cradle.
