Even in total darkness you can read the minutes and seconds on GraLab's Model 300 Darkroom Timer. It is used in industrial/commercial photo labs, graphic arts, printing, 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.

Two, three-wire receptacles can control an enlarger or printer and safelight with a combination time/focus switch.

Rubber base pads, wall mounting keyholes and a recessed hand grip on the 7-1/2 x 7-1/2  x 2-1/2" polycarbonate case give you multiple placement choices. This item requires a plug adapter (sold separately).

        This timer is an important and very easy to use item in my darkroom.From now,the timing of film development in total darkness especially sheet film in tanks should be the simplest method.
