Batch Timer is an enhanced timer.
It will estimate and notify you when a batch job will finish.

Imagine that you are making a lot of copies of a document consists of several pages.
You may think you want to leave the machine and come back exactly when the copy job is done, rather than waiting in front of the machine without doing nothing. 
Batch timer will tell you when the copy finishes.

Use center button to set the duration of one copy. Push the button when one copy finishes.
Then, push again when another copy finishes. Batch timer will remember the duration.

Use up and down button to increase or decrease a number of copies.
Remaining time will be calculated and the count down start automatically.

Simple, but all information are displayed without button operation.

Second hand is displayed for about one minutes when shaken.
Date changes its position on the dial so that it is not hidden by hands.
Battery level is always displayed by ticks on the dial.
When Bluetooth is disconnected, watch vibrates and date will turn red.
When charging, ticks on the dial turn red.
Watch face is redrawn on every 10 seconds, so that you can read the time below the precision of one minutes.
Color around the dial changes on every 10 seconds.
