This Thing is Improved version of Thing 5518998 by Shiura. Cudos to Shiura for this awesome work but;

1- Minutes hand - minutes gear connection corrected and simplyfied
2-Hours hand - hours gear connection corrected and simplified
3-Clock's firmware's bugs fixed.

I strongly Recommend, Index Spring must be printed with PETG
