The best laboratory stopwatch!

The GRALAB 300 counts down the time accurately during the development of your films. When the time is up, it "buzzes".

This chronometer has two hands:
- one for the seconds: one revolution around the dial represents one minute,
- one for the minutes: one revolution around the dial represents one hour.

The dial is visible in the dark thanks to its fluorescent clockface. It is recharged by incandescent light and remains visible for 20 to 30 minutes.

It can be hung on a wall.
