The subtle "wiggle" animation that the second hand makes after moving doesn't fire when it hits 12. Literally unwatchable.

In its defence, the code actually specifically calls that edge case out and justifies it:

    // Calculate rotations
    // We use a cumulative calculation logic mentally, but here simple degrees work because of the transition reset trick or specific animation style.
    // To prevent the "spin back" glitch at 360->0, we can use a simple tick without transition for the wrap-around,
    // but for simplicity in this specific React rendering, we will stick to standard 0-360 degrees.
    // A robust way to handle the spin-back on the second hand is to accumulate degrees, but standard clock widgets often reset.

The Swiss and German railway clocks actually work the same way and stop for (half a?) second while the minute handle progresses.
