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.

However, as we will prove for the very first time in this article, this is not the case. It is clear that at least some of the digits of the movement serial number are a counter, but to-date we believe that no-one has ever managed to crack exactly how that counter functions over the production life-span of the reference. Without a clear and logical explanation behind the movement serial number counter, we are reliant on the case serial number counter to estimate production numbers.
