I think it’s fair to say that any watch which replicates another instrument is a kind of gimmick. Dashboard watches come immediately to mind, as do more specific gauges like altimeters and speedometers, and even digital recreations of vintage video game consoles, and so on. Rarely do I find these gimmicks interesting or original, but the Reservoir Sonomaster Chronograph is an exception to my general disregard for such timepieces.
