E

Elapsed Time

The actual time taken for an object to travel over a specified distance.

Elapsed Time Rotating Bezel

A graduated rotating bezel (see rotating bezel) used to keep track of periods of time. The bezel can be turned so the wearer can align the zero on the bezel with the watch's seconds or minutes hand. You can then read the elapsed time off of the bezel. This saves from having to perform the subtraction that would be necessary if you used the watch's regular dial.

Engine Turning

Decorative engraving, usually on a watch dial.

EOL

End of Life. In quartz movement, the end of battery life is indicated by the second hand, which starts to jump every four seconds. The battery should be changed immediately.
