Tudor 2824-1

The Tudor 2824-1 is an automatic movement based on the ETA 2824-2, launched in 1982. It was Tudor's first-generation variant of the widely used ETA 2824 caliber, bearing the alternative designation ETA 2824-1. As a non-in-house movement, it represents a period when Tudor relied on Swiss ébauches rather than developing proprietary calibers. The movement was discontinued as Tudor transitioned to its in-house MT series beginning in 2015.
