Practical?

What's the battery life?  How accurately can you read a watch dial?


How good are modern watches?  How do crystals compare with mechanical?  Where 
is the crossover point between watch accuracy and human read-it accuracy?  Is 
that before or after the CASC watch runs out of battery?

I suppose you could put it on the charger every night, next to your cell 
phone, but then I could make a crystal watch that connects to a "charger" 
stand that also sets the time.
