A very rare bird from 2013, this patented pusherless chronograph from Habring² allows you to start, stop, and reset the chronograph entirely through the crown (see video).
Movement side affords you further view of the COS mechanism and the automatic winding rotor is engraved with instructions as to which direction to rotate the crown to operate the chronograph.
This stainless steel case measures 42mm x 14mm and is in excellent condition.
