Abstract:
An analog chronograph timepiece has a main plate and a setting stem for correcting time information. Defined at the main plate are a reference vertical axis line passing through the rotational center of the main plate and disposed parallel to a central axis line of the setting stem, and a reference horizontal axis line passing through the rotational center of the main plate and disposed orthogonal to the main plate reference vertical axis line. The main plate has regions disposed relative to the reference vertical and horizontal lines and in which a time coil block and first and second chronograph coil blocks are selectively arranged.
