Reference photography not yet on file

A specification, not a model. The identifying evidence is the caseback: GG-W-113 watches are stamped with the specification number, a part number, a contract number and a date. Hamilton is one of several makers who built to it, so the caseback alone does not establish the manufacturer.

Some specifications for this reference require verification against manufacturer documentation.
