| A wrist watch having a cursor ring rotatably mounted thereon, said cursor being formed with a first laterally projecting portion having a cursor line thereon for setting scales on said watch, and a second projecting portion for manual engagement for the selective rotation and positioning of the cursor ring. A bezel having graduations on its surface may be rotatably mounted relative to a fixed graduated circle on said watch with the first projecting portion of the cursor ring in overlapping relation therewith.

| There is disclosed apparatus for automatically calculating spectral bandwidth in a monochromator of the type having slit and wavelength drive mechanisms. A stationary scale member is scribed with indicating marks related to slit width. A sliding scale member is driven by the wavelength drive mechanism to slide juxtaposed with respect to the stationary scale member, the sliding scale member having a surface upon which are scribed indicating marks related to dispersion of the monochromator, the scribed marks of the sliding scale being calibrated with respect to the scribed marks of the stationary scale to indicate on the sliding scale the dispersion of the monochromator opposite a given slit width indication on the stationary scale. A moving indicator driven across the scribed surfaces of both scale members by the slit drive mechanism has a reference line to continuously indicate the monochromator slit width on the stationary scale and the corresponding dispersion on the sliding scale as the monochromator spectrum is scanned.
