It is my understanding that the Triple Date Moonphase Watch had two generations:

First generation :
- movement hand wind ref. 905 cal.12S or cal.1100
- movement automatic ref. 908 cal.1402

Second generation :
- movement automatic ref. 742-908 cal.74 silver case
- movement automatic ref. 743-908 cal.74 gold plated case

Does anyone know exactly when the 1st generation was introduced, and how long after that until the 2nd gen was introduced?

I have seen the catalogue from 1955 that shows a 1st gen 905 and 908; however, the catalogue from 1953 did not have them.

Hello, I am looking for a black dial with silver indexes for a triple date moonphase ref.908 automatic from the 1950's. Exactly as shown in the picture. Please let me know if any of you have one for sale or know where to buy one. Thank you and best regards. Dawid.

Thank you gentlemen. I wish all users good luck in expanding their zodiac collections and much health in the coming New Year.

Per the 1990's catalogs that is the smaller auto version. Some may say womens or boys, or just for a smaller wrist.

I recently acquired this Zodiac from the 90s. I believe it's from the era where there was some Tag crossover in design. The ref number on the back doesn't really net much online (beyond the auction I bought it from). I can find this design in a quartz version without the 'automatic' designation. I can also find a white dial auto version.

Any further info would be appreciated. I'm curious if it's technically designed to be a women's watch since it's pretty slender.

Either way, thanks for your help!

 

Thanks Yuriy! I forget about the push in quick set, so it would be a different stem, as you say.

Stem for regular 70-72 won't fit 76 as the last has a quick set date complication.
There are two major differences of stems for this family:
- no quick set: 70, 72, 70-72, 74, 75, 78
- with quick set: 72B, 75B, 76, 88, 86

Definately the correct rotor.

Per the service manual they should be the same stem, IF using a genuine Zodiac parts (HA!). While I do not do repairs, I think aftermarket stems fit many models and need to be trimmed to fit.
