Omega Speedmaster 1861: The Heart of the Moonwatch Legacy
The caliber 1861, a manual-winding chronograph movement, is arguably the most famous movement ever associated with the Speedmaster Professional. A direct descendant of the caliber 321, which powered the Speedmaster during the Apollo missions, the 1861 represents a simplified, yet robust, evolution. While the 321 was a more complex and column-wheel chronograph, the 1861 opted for a simpler, cam-operated mechanism, making it more efficient to produce and maintain. This simplification, however, didn't compromise the movement's reliability or accuracy – qualities essential for a watch intended for use in extreme conditions.
