actually reading about this, im not sure on the actual numbers but it was a lot. Two things to consider is due to the fact these were inexpensive most people wore these as daily watches and there are not many watches in really good condition.
Let's use just the Pogues -6000,-6001, -6002, -6005, -6007 & -6009 Figure 11 year run, 5,000 per month every month average, that's 660,000 Give me more per month if you want.
Do the same for the -6010/6011/6012/6015/6019 Another 660,000 please We're at 1.3 million and have every other variant to count, many are low manufacturing references.
I'll toss out 2 million 6139s were made. Purely a 1 minute analysis absolutely no facts to back it up but an order of magnitude SWAG without stopping to ponder much.
