Clip Watch by Mac Funamizu

Clip Watch is a new concept from Tokyo, Japan designer Mac Funamizu. This button-looking watch was designed to be easily accessable during cold winter. Clip Watch attaches to your coat or on your bag. Tap the clock’s face and it displays the time and date and then switches off again. Clip Watch features solar panel that harvests clean energy and eliminates the need to change batteries.
