Abstract

An electronic watch movement including a base plate having a pair of opposite major surfaces. A calendar ring is disposed confronting a first of the major surfaces, and a circuit board is disposed confronting the second major surface. The calendar ring has a narrow central annular portion, a wide peripheral skirt portion circumscribing the narrow central annular portion and a circular step portion extending between the narrow central annular portion and the wide peripheral skirt portion. The skirt portion of the calendar ring is spaced further from the base plate then the central annular portion of the calendar ring. The base plate has openings therethrough opposite the skirt portion of the calendar ring, and electronic watch components are mounted on the major surface of the circuit board and extend through the openings through the base plate beyond the narrow central annular portion of the calendar ring toward the wide peripheral skirt portion of the calendar ring. The electronic watch components are oriented to minimize the thickness of the electronic watch movement.
