ISA Caliber 8176/2050

The ISA caliber 8176/2050 is a quartz movement with a small seconds subdial and a central 24 hour/GMT hand.

Swiss Made or Far East?

The movement shown here was found in an Invicta Russian Diver watch that says “Swiss” on the dial and caseback, however, the movement itself says China and Far East. ISA officially lists this movement as Swiss Made and Far East Ass’y. This is ambiguous, and it’s unclear why they use the term “Far East” and not China on their documentation.
