A snap-together electronic watch module frame and assembly includes a plastic front pod member having a first recess to receive and locate the electrooptical display, a rear pod member having a second recess to receive the timepiece battery, and an intermediate pod member sandwiched therebetween adapted to carry and position a printed circuit board with an integrated circuit chip, oscillator, capacitor, conductors and the like thereon in preselected relation to the display and battery. The module assembly is held together by resilient gripping arms molded into either the front or rear pod member snap-fitted onto shoulders molded on the other pod member. The intermediate pod member is molded to include on or more depending alignment legs adapted to fit in alignment holes molded in the rear pod member to properly position the circuit board components relative to the display and battery. The intermediate pod member also includes a central opening to receive the integrated circuit chip and form a dam therearound into which encapsulant can be poured to protect the chip, elongated guide slots in opposite edges into which flexible connectors are positioned to electrically connect the display and printed circuit board contact terminals and, if desired, a backlight locator.
