Inside of the case back should be a reference number. It is what we want to see.

Adding some details.

The case width is 34mm

Case thickness is 10mm



I'm guessing it is from around the 1960s from looking at family photos

Thank you for letting me join the forum!

Really hoping for some help here.

When going through my late grandad's belongings I have found a beautiful triple date moonphase Zodiac... that's empty. There is no movement inside.

I want to get it up and running as a suprise for my Dad, but I've seen so many conflicting things online about what movement i should be looking for.

I have done some projects for my friends and myself, but I always started by knowing what movement should be inside the watch!

I have a list from hours of scouring the internet of what movements it could be, and would really appreciate some help.

A Schild 1402 
ETA 1164
Venus 203
Valjoux 90
ETA 7751

Please help. Have I misunderstood and I could actually use any of these movements? That seems very unlikely, but they do look very similar! I just don't want to mess this up.

Does 304 mean 30.4mm?

  

Hello forum members. Can anyone help me with this. I am seeking  watch crystal for my Zodiac Glorious Datagraphic. The dimensions are:

Diameter 304
High dome.
It must have a ROUND calendar window, as per the original.

If anyone has one for sale can you drop me a line on ndpadgett@btinternet.com.

Thank you.

Thanks bumo79. I learned a lot of new info here. Much appreciated.

To my knowledge, the original bracelets for Zodiac were produced by only 5 companies. They were :
- JB Champion (popular in the US)
- NSA Novavit (Swiss brand popular in Europe, legend producing for companies like Certina, Rado, Favre - Leuba. I have 4 Zodiac watches on this bracelet)
- Chatelain (Swiss brand popular in Europe, I have 10 Zodiac watches on this bracelet, they also produced for Omega, Zenith, Favre - Leuba)
- Kreisler Stelux (Hong Kong brand, founded in 1963 popular in Asia, produced for Zodiac)
- Drema Kevin (Hong Kong brand, I know nothing about it,
  but I have the original Astrographic on this bracelet, not just the clasp.
I have never seen the design from your photo. Beware of no-name bracelet type scams with original clasp.

I have an SST type Zodiac Day Date & bracelet is short one link.
Looking for one to match existing links from Zodiac "Bear Hong Kong" bracelet.  Early to mid'70's.
Looks like I have 5 good links on one side vs. 4 on the other. From pic, the side with 4 links shows a sizable difference between link closest to clasp, and one 2nd closest to clasp, like it was removed at one point.

Just a collector (I've bought watches here from Butch, like a lovely orange Sea Wolf back in 2010). Just a fellow Zodiac fan looking to make this watch complete.
