New here and reading spec sheets for the first time. Four terms keep tripping me up: complication, caliber, jewel count and power reserve. Short definitions would help, and so would a note on which ones actually matter when comparing two everyday watches.

Caliber is the movement's model designation, like a part number. Two watches from different brands can share the same caliber family with different finishing or regulation. On a spec sheet it tells you what's inside and roughly what service parts are available. It doesn't tell you how well that particular example was adjusted.
