A very special solid 18kt yellow gold Omega Constellation. On the outside this looks like any other hidden crown Omega Constellation, save perhaps for its yellow gold case. Setting this Constellation apart from others however is its British manufactured case hallmarked indicating its origin in a little city known as London. The fancy "S" makers mark was first registered into London's Assay office in 1946 by a gentleman by the name of David Shackman. The registration location for the corporation in conjunction with hallmarks indicating the assay office all correctly match and result in a very neat vintage watch indeed.  ABOUT THIS WATCH:  MANUFACTURER: Omega MODEL:  Constellation REFERENCE:  168.5004 SERIAL: 269XXXXX YEAR: 1968 CASE: The 35.5mm solid 18kt yellow gold case is in good shape.
