Use Blink to add a unique and decorative touch to any wall. This wall clock mechanism operates on a quartz clock movement that ensures precise and maintenance-free time measurements. Blink’s metal time indicators and the number 12 mount individually to the wall with easy to paste adhesive and the clock mechanism mounts with a screw or nail. The size is customizable depending on your preference, however if you aren’t feeling adventurous, Blink does include a preset wall template (100 x 100 x 4cm). All you need is 1 AA battery (not included) and you are set.
