The caliber 440 is 17 jewels and is 8-3/4 x 9-3/4 ligne or 19.4mm x22mm. It is the third Curvex movement that was produced by Gruen and shares parts with the caliber 430 and 435. This caliber is clearly marked with the number in the space between the barrel bridge and the balance cock.

All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me
