I have not been able to find any info regarding an oval faced Zodiac I got in the mid 1970's. It is SS, brushed SS face, vertical rectangular hour markers, plus day and date at the 6 O'Clock position. It is marked "Automatic - Antimagnetic - Swiss" and "Water & Shockproof" on the back, with the scales on the top of the oval on the back and "Zodiac" at the bottom. It has the original SS bracelet.
Photo 9 in the Miscellaneous Gallery is very close to my watch, except mine does have the day and date. It has always run great, which makes me believe it is authentic.
I can post photos if anyone has an interest. It's not on the "For Sale' list yet simply because I have so little info on it. Any info would be very helpful and appreciated. It should go to a good home...
Welcome! Sure, go ahead and post a picture.
