The Timex M67 watch movement, produced from 1972 onwards, shares similarities with the 7801A but specific differences are unknown. It features an electronically controlled balance motor, a sweep second hand, and a day function that can be quickly set by repeatedly pushing the crown with the 12-hour position at the bottom; the day display is available in two languages. Additionally, the date function can be quickly set by repeatedly pushing the crown with the 12-hour position at the top. The movement allows for the zero reset of the second and minute hands by using the pusher at 8 o'clock, and it includes a hack feature.
