We have used an “Airpot” for many years. For those who are not familiar with airpots, they are tall insulated containers for water or other liquids (especially coffee). We find it convenient to have hot water literally at the touch. We make cocoa. And we use it for an immediate rinsing of cooking and eating utensils.
The original reason for this to help farmers who needed daylight to do their chores. But more recently they have powerful lights on their implements.
We have three electronic watches—a Casio F-91W, a Casio PERSONAL TRAINER, and a SEIKO ALARM PULSE METER CHRONOGRAPH. We cannot find any helpful information on the Web to help us change the time shown on the watches.
