Michael, yet you are right.
Please find attached a comparison between an ETA 7750 and an ASIA 7750 Clone (3LZF2)
Drawings revealed:
---------------------------------------------------------------------
ETA 7750
Hour Hand -> 2,00 mm
Minute Hand -> 1,20 mm
Central sec. Hand -> 0,25 mm
Small hands -> 0.18 mm
---------------------------------------------------------------------
ASIA 7750 (3LZF2)
Hour Hand -> 2,00 mm
Minute Hand -> 1,20 mm
Central sec. Hand -> 0,22 mm
Small hands -> 0.22 mm
---------------------------------------------------------------------
But by measuring the existing damaged 3LZF2 the diameter of the small hands are only 0.18 which is matching with the ETA movement ????
But my biggest concern are because of the central second hand 0,22 (clone) to 0.25 mm ETA!
There is a difference from appr. 0.03mm.
Is it possible to enlarge the central second hand by 0.03 mm.
This is 13 % of size!
