If you are shopping for a replica Speedmaster, the movement choice often comes down to Cal 863 versus Cal 861. Both are hand-wound, cam-actuated chronograph designs based on the classic Omega architecture, but they differ in finishing and visual character. Our pick is the Cal 863 replica for its brighter, more refined appearance, while the Cal 861 remains the better match for early-1990s references.
