Dials shown are for the Ball and Co ORRS Watches thru 170K
I have not shown any dials relating to Brotherhood or P&L movements that are also found in these runs.
I would expect them to follow the same pattern but have noted two BLF's early in the 42k run that might be exceptions. They have wavy 3 earlier type dials. Later BLF's in the same run have the expected flat 3 numerals.
The 90K and 170K runs also have commercial std movements and those dials are not pictured either.
Ditto the RRWCo dials found in the 90 k run
Somewhere in the170 run, movements and dials transition to Ball Watch Co
