This is the closest dial configuration that I have found (on US cased Longines with 23Z movements; exists in silver and black finish). An important difference is obviously the subsecond configuration and the fact that it is on a manual movement. The markers and hands are similar. We will have to wait that another similar watch emerges to learn more about this configuration. I have followed your advice and sent an email to the rochester fire department. Not too hopeful but who knows... I will let you know if they have a truckload of those in their basement
