Kurz produced around 1500 units from 215500 to 217000; he most certainly did not produce 500 units/month.
Only about 15000 units can be dated to ww2.
If 2000 watches were produced from June to the end of November 1942 that means around 330 watches/month, perhaps 10 watches/day which is not impossible.
At the height of production I think they made around 600 units/month. In the later part of the war watches were produced not only at Glashütte but also in other locations with a different workforce.
I will revise my chart as we accumulate more data. Dials may tell the complete story. Perhaps important collectors who have many Tutimas already have that knowledge
