The Schild & Co 280 watch movement, manufactured between 1937 and 1970, is a manual-wind chronograph movement with a 60-second counter and 30/45-minute capacity. It features a sub-second function, a Tag pusher at 10 o'clock, a date hand at 6 o'clock with a pusher at 8 o'clock, and a month indicator with a pusher at 2:30 o'clock. The movement has minor differences from the Landeron 180, and parts between the two are sometimes interchangeable. It was widely used during its period of production, with over 3.5 million units manufactured.
