The S.G.T. caliber 100 is a vintage handwound mechanical lever style movement with 17 jewels and a direct central seconds hand.

There is also an “E4” designation engraved below the caliber number. The meaning of this “E4” is unconfirmed.

SGT 100 VS FE 140:

You may also see this calibre referenced as FE-140 (by France Ebauches). As such, there are different variants featuring calendar complications. Note: the drawing above is actually from a France Ebauches tech sheet for the cal. FE 140 C.

  • FE 140 (140 C) – No-date
  • FE 140-1 (140-1 C) – Date
  • FE 140-2 (140-2 C) – Day/date

Caliber Corner has still not confirmed the SGT-100 caliber numbers for the calendar versions (perhaps it is SGT-100-1?). If you know for sure, please add them in the comments below.
