The face plates containing the gels were swapped in each scene with a different pre-set month. If you look closely in some scenes before the time circuits light up you can see the month is already present but not lit. On modern time circuit displays most people use off the shelf alphanumeric displays that you can find on Newark.com, mouser electronics, etc.
The information in this thread doesn't add up. The CR-852 enclosure is 8.5 inches wide. If the digit height is 0.8 inches, then each digit is 20 mm wide. 20 times 13 digits is 260 mm. That is 10.23 inches without any spacing at all! Either the enclosure is not the CR-852, or the digit height is not 0.8 inches. Or perhaps both are incorrect.
