Haven't worn this one in a few years. It's beat, but it's serviced and keeps suitable time and it has a neato swan logo on it.
I don't know what the case is made of. Seems to be aluminum rather than plated brass. No yellow (or green verdigris) to be found top or underside in all the wear and corrosion. Probably was once an attractive Record watch.
I notice the SARB017 prices coming back to earth. For a while they were selling crazy on Reddit. Although I keep it on a bracelet I think a good leather band makes the dial pop. Cool clouds over yonder
