GE clock radio date codes.

Interpreting GE 4 digit date codes.

Some of you may know this ... but I thought this was interesting.
Someone on YouTube asked me when the GE 7-4305D was made. I researched in on newspapers.com and it seems the rolling wheel version (7-4305) came out in 1978

and the 7-4305D and 7-4305F (flip clock versions) in the early 1980s

The date codes on these clocks is a 4 digit code.


It seems that the second digit corresponds to the year. They must have started in late 1970s. The third picture shows an 8 so that would be 1978 and the 6th image would be 1979. The others are from 1981 to 1984. These match up to what I would expect as the models move towards the A to the D and F versions.
The first digit is the day of the week. You'll only see from a 1-6 here designating Mon-Friday (I guess no Sundays?). The last 2 digits are the week of the year. You'll never see higher than 54 here.

Let me know what you think.

After all my "code cracking" I did see on antiqueradios.com that someone mentioned that this was their speculation for the date codes that were in use in from 1959-69 on other electronics. I could have saved some brain cells if I saw that first.

Very good info, Mackey. I always wondered how they encoded their dates of manufacture at GE. Honestly, I haven't restored too many of the GE units so haven't paid close attention to them.

They're not all that exciting visually, but they're built very well.
