Interestingly, even on these unusual (but, as Mr. Bloke says, cool) Citizen movements, they still feel obliged to put the stupid and worthless 24 hour hand on.
That's unfortunately the case with a shitload of Citizen chronos. Alas, Seiko does the same with the cal. VK-64. Still, if I really had any beef with Citizen's chrono movements, it wouldn't even be the 24h subdial, but the chrono reset. The reset in Citizens is just ridiculously fucking slow. Any current ETA or Ronda quartz chrono has it working way better, with the ETA-made VHP (for Longines, but also used by Rado, AFAIK) nailing it with an instant, snap reset.
I always hope for the best. Experience, unfortunately, has taught me to expect the worst.
