One of the 40 decommissioned EZM2s - the GSG9 was added to the dial once Sinn took the 40 back from the GSG9 and serviced them priory to sale.
When it goes back for service/battery change, I am tempted to ask them to put a NOS EZM2 dial on it - the issue number is on the back, so I'd rather have it looking like it was when in service.
