The A Michel 454 watch movement, introduced around 1945, features a straight lever and a unique train arrangement. It involves the 2nd wheel driving the 3rd wheel conventionally, while two additional wheels (C and D) are positioned between the 3rd wheel and the sweep-second wheel (E). Instead of directly driving the escape wheel (G), the sweep-second wheel (E) engages with another wheel (F). The movement lacks space for a large balance and barrel due to the extra pinions and wheels, which also increase costs. However, no noticeable advantages are associated with this arrangement. In terms of functionalities, the A Michel 454 movement offers manual winding and the presence of a sweep seconds hand.
