FactoryPolerouter Date, Sub, NS, Genève and Super executions
Universal Genève sold the Polerouter under numerous suffixes denoting date function, dive specification, dial execution and market. All are factory configurations; the suffix is part of the identification and is not interchangeable, and the catalog does not yet hold the full reference map for them.
Component compatibility
What this reference is documented to have carried, and in what capacity. A service part is the manufacturer's own work; only a counterfeit classification is a finding against the watch.
