Yes, you right. They have 45mm and 40mm. But i put on AR locater, but no AR on the map. So i think Zenith do not distribute watches in my country. Totally different brand Arnold and Son. Only 1 AR in my country. Omega for example, on every street corner.
I, too am interested in a Defy (the Defy Classic Skeleton black ceramic), but am also intrigued by the new Chronomaster Revival "Shadow" (even if it perversely lacks a minutes/seconds track).
