I think that there are a number of similar models that share that same case with variations in dial, hands, movement etc. Most you see are either 'Polerouter Geneve' or 'Polerouter Compact'.
The Polerouter Geneve had a microtor movement, typically a Cal 218 or Cal 69.
The Polerouter Compact had the Cal 256 'super-microtor' Movado movement.
Presumably yours is not a Polerouter because it doesn't have an automatic movement.
Here's my Polerouter with Cal 218-2 movement.
