For the most part the 5512s from this period have the 4 line dial version featuring the “classic” coronet. The first two lines of text are gilt print or gold text and the 2 lines of SCOC text below in silver. The main difference between the 5512 dials from 1964 and 1965 compared to those from 1963 is the absence of the underline in the later dials. In addition, in contrast to the earlier 5512 examples with “SWISS” only at the bottom of the dial, the dials from 1964 and later have “SWISS T<25” printed at the bottom, signifying the use of tritium for the hour markers.
