Might it be an elapsed time feature. Press the stop button to record the time, then press it again at which time the sweep seconds hand jumps ahead to register the elapsed time for the guy running second. Used to record the time of the first and second place finisher. Normally, pressing the stop/start button a second time, the sweep hand carries on from where it was stopped. Anyone with a better idea?
My weekend just began after an early tour this morning. Sitting on my front porch, watching the rain and enjoying a cigar. Temperatures and humidity finally broke so I’m enjoying a cigar and solitude, contemplating dinner.
