The Zentra 154 watch movement features a mounting frame that includes parts of the date assembly and serves as the highest component of the calibre. It incorporates an indirectly driven minute hand that enables a large balance. The movement is equipped with two barrels that are connected in parallel, ensuring optimal utilization of available space. In a configuration with 26 jewels, five hole jewels are used for the horizontal guidance of the date disc, and four cap jewels facilitate the vertical guidance. The movement is designed for manual winding and offers functions such as day adjustment within a range of +/- 24 hours and date adjustment achievable through a pusher positioned at 2 o'clock.
