Offered here is a Gralab Model 300 Classic Electro-Mechanical Darkroom Timer Unused! With this Darkroom Timer. Even in total darkness, you can read the minutes and seconds. It is used in industrial/commercial photo labs, graphic arts, printing, and hobbyist darkrooms and is probably the most popular darkroom timer of all time.
Set by seconds, minutes, or a combination of the two, GraLab's exclusive dual-cam system gives you exact timing over long intervals.

The plastic boot over the power switch prevents corrosion from chemicals or water.
