This one dates to April 1982. More, very interesting, information on the railway watches and their use can be found here. To make sure the watch keeps good time, it was set up on a quartz tester. The spec for this movement is. The final photo shows the measurement.Around 0.2 sec/day is 6 sec/month. As the watch is not thermally compensated this will not hold for all conditions. The point of the test is to show that not only is the watch running, it is also running well with great accuracy. This watch shares the same quartz circuit (and same movement possibly) as the Seiko 7548 and 7549 dive watches. The circuit board bears the 5 jewel designation. It would require a swap of the circuit cover which in this case is marked 7550A. Never had the need to delve that far. This is a watch in used cosmetic condition. Minor ding on the caseback which I have tried to show in the photos. Nothing major, just wear and tear. No obvious marks or scratches. Please examine the photos carefully. The time sets as it should.
These movements are adjustable and are capable of very high accuracy. I do not know the service history of the watch. You should assume it will need a service at some point.
Overall a good usable watch. Included in this listing is the watch itself with the black lanyard. The package will weigh under 0.25kg so the following rates will apply. UK, France, Spain, Sweden etc.
