In a previous article that detailed the different variants of the reference that were produced over its production lifespan, we mentioned that it is generally believed no more than 36, units were produced of the model. Since the publication of that article, we have continued to undertake research to try to establish a better estimate of production numbers, and also try to get a more accurate handle on the relative numbers produced across the three major dial configurations of Printed, Carved, and Raised logo dials.

Stamped on the inside of the case back of the watches can be found the case serial number. Comprised of seven characters, we explained in the previous article how the first two characters of the serial number can be used to determine the month and year of production.
