A timer indicator or chronograph is described. The chronograph functions according to chromatographic principles to develop a perceptible visual image or pattern on an indicator panel or display area, which serves as a means to monitor the relative amount of time that elapses. The chronograph includes a self-contained reservoir for an activating agent, which once activated creates a mobile front that traverses the indicator panel substrate from the reservoir to a distal end at a predetermined rate. The chronograph may be used as a stand-alone device or may be incorporated as part of various articles or products, for instance, as either a training aid or as a dryness indicator. Methods for using and making the chronograph are also described.
