Two new zenith in the collection. A defy in very good condition with an interesting dial. Reference 01.1500.380 A Zenith automatic in gold with an engraving that I've never seen. "Seals twice". Perhaps especially waterproof. I think it's a Monocoquecase. May be the case is made in the United States.
Congratulation Very interesting dial never seen before.... Do you have more information about the Defy?
Unfortunately I have no further information. Asimilar clock in blue has the caliber 2562PC and is water resistant to 300m.
