A chronograph is one of six functions here, alongside a perpetual calendar, dual time, alarms and radio synchronization, all running on light behind anti-reflective sapphire and rated to 200m. Nothing else at this price does a fraction of it.
45mm across, and the module is the watch: when Citizen stops supporting the U680, no case quality saves it. That is the trade for this much capability, and we score it rather than hide it.
It sets itself by radio, runs on light and is rated to 200m behind sapphire — and it is a module, not a movement. When the module stops being made, the watch is finished, however good the case still is.
