Cases can be found with a variety of configurations. The center watch has a parkerized
case, and the other two are plated and showing wear. The first has no markings, but has a
987A movement with a dust cover and a screw back. The last has a snap back and is most
likely later than the first.
The 987A has sub-seconds, and the later 987s and 2987 both have center seconds. The center seconds was more desireable simply because it was easier to read. None of these variations had the hack function found on later watches.
