Ob es bei diesem Model um ein Original handelt, kann ich nicht sagen, denn ich bekam diese Uhr geschenkt, daher sind keine Papiere vorhanden. Alle Chronofunktionen einwandfrei, Automaticwerk mit Glasboden.Käufer trägt Versand-und Ebaykosten. Nur per VORABÜBERWEISUNG, keine Schecks, keine Nachnahme.

I TRANSLATED THIS TO:

I cannot say whether it acts in this Model around an original, for I was given this watch, and therefore no papers available. All Chrono functions work flawlessly, Automatic work with glass ground. buyer delivery carries-and Ebaykosten (not sure what that is). Only per VORABÜBERWEISUNG (not sure about this word), no checks, no c.o.d.

The key sentence is:

I cannot say whether it acts in this Model around an original, for I was given this watch, and therefore no papers available.

That is usually translated to being a fake. Many fakes can have working chronograph functions. Sellers usually state it was given them as a gift, to be "legally" able to post on e-bay.
