Omega 552
ProbableThe no-date member of the family. Its dated sibling, the 565, is otherwise closely related, and a Seamaster of this period may legitimately be found with either depending on whether the reference carried a date window. A 552 behind a dialled date window, or a 565 behind a dial with none, is a mismatch worth resolving.
