Zenith ’70s model codes : movement numbers
Project : a list of Zenith ‘model codes’ (introduced ca. 1972) and the movements behind them
The first two numbers denote the material of the case and the strap or bracelet.
For instance : 01 xxxx xxx or 20 xxxx xxx :
01 is the code for a steel watch. 20 is the code for a gold plated watch.The last three numbers denote the movement. This thread focuses on those movement codes.
Notes :
– these codes could also be listed with a dot after the second number, e.g. 290 = 29.0.
– movements from other manufacturers (such as ETA movements) were modified by Zenith.
– this is a list of movements used in the 1970’s. Movements for ladies’ watches (though less important) are included.
Looking forward to corrections, additions, suggestions !
