The technological solution for the outdated watch clock system (electronic checkpoint instead of key).
Each Button (checkpoint) is basically composed of an electronic circuit with a unique laser-recorded serial number in a stainless steel casing.
The Buttons are highly durable, extremely resistant under almost any condition inside or out, and do not require electricity.
They are ideal for hostile environments with dust, rain, snow, electromagnetic fields, etc.
