my only issue is that it cares if you are off by 1 minute, meanwhile in the real world a lot of analog clocks have continuously moving minutes and a lot of others have ticking minutes (they only move right at the minute mark).
For clocks, however, there is the iconic Swiss railway clock [1], which dates back to 1944 and has a jumping minute. For those, however, the jump is actually meaningful in itself, in they're synchronized by a master clock that has a one minute impulse, and the jump is actually the moment of the impulse.
