The caliber 707 is a 15 jewel movement and is 12-1/2 ligne or 28.4mm in diameter. The caliber 713 is a 7-jewel variant of this movement. Although these are commonly marked on the pillar plate with the caliber number, usually in the space between the escape wheel finger and the balance wheel, occasionally they are unmarked.

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

The 707 is based on the Lavina 28. The ebauche was used by several makers. I have a West End trench watch using this movement as well.
