    Excellent product! I did not want a smartwatch, but this one is quite advanced. Battery is charged by solar cell, time is automatically synchronized after pairing with phone via bluetooth and if you click the button on your watch (search) your phone starts making sound.

    • Many options
    • Solid
    • Beautiful appearance

    Uitstekend product ! ik wilde nml geen smartwatch, maar deze is best geavanceerd. Batterij wordt opgeladen door zonnecel, tijd wordt na koppelen met telefoon via bluetooth automatisch gesynchroniseerd en als je op het knopje op je horloge klikt (search) gaat je telefoon geluid maken.

    • Veel opties
    • Degelijk
    • Mooie uitstraling
