Omega 1863
ProbableMechanically equivalent to the 1861; the difference is finish, specified because the movement is visible. A 1863 behind a solid caseback, or an 1861 behind a display back, is a configuration question worth asking — and is sometimes explained by a legitimate service parts substitution.
