I thought it would be interesting to collect the serial numbers of the early 300 no T and black lungs doxa. I have come up with three so far.
There are two sets of numbers on the watch. The first numbers is 11889-4 and it is a common number on all three watches that i have collected.
The serial number on my black lung is 6609446
The serial number on my Sharkhunter is 6609465
The serial number of the 300 no T that sold on ebay 6609464
I know that there are no records on how many watches were made by doxa. But if we can collect serial numbers maybe we can narrow the numbers of watches produced. Brian
