An original WW2 KM marked Zentra Wristwatch. A lovely watch in original condition. 334 (Albert Kratz GmbH Minden) which is 15 Jewel shock proof. Note sent back with parts replaced is in photos and will be included with the watch. Crystal, crown and setting lever spring were replaced.
Once again, see the note. I believe its its wonderful condition and has previous service marks on the inside of the case back from the 40's.
