This is a very unique piece with completely open papers which makes for a great gift for someone, or even for yourself to put your name and birthdate on the papers for example. The Z erial dates this timepiece to a 2006/2007 production run. It was later discontinued in 2010 and has been increasing in value ever since. It is in excellent preowned condition and presented as a full set.
