Quartz chrono movement with 30 min subdial?

[Colin63]

For once I'm not talking made up nonsense (just true nonsense). I've a sensitive sense of smell anyway but here's an example: if I'm toasting spices in a pan, I know when they're done because the smell changes from warmed-through to kinda-toasty. And so I don't need to keep peering in the pan, the smell will reach my nose when it's time.

Similarly if I've left rice cooking in the kitchen with a bay leaf in, when the smell of bay leaf coming from the kitchen reaches a certain level I know the rice is done.

I can tell when the toast is smoking!
