The Focal Plane Meter shows higher speeds than the standard Bee, it was also easier to read. In use the actinometer value is found, the plate speed is set against that value, the shutter speed / aperture pairs can then be read. The dials were not interchangeable with the ordinary Bee.

One of the last Watkins meters to be introduced, the Fall was intended for use with newer cameras then on the market having faster lenses and shutters. The case of the Fall differs from the Bee and the dials are not interchangeable. After setting the plate speed and actinometer value the shutter speed / aperture pairs can be read.

In use the film speed is set against the actinometer value that has been measured, the aperture can then be read against the shutter speed of the camera. The price of 7/6 dates this example to 1919 or later.

Produced in two series for f8 and f10 lenses.
