Blue steel hands for the seconds and hours, a red hand for the minutes.  Plain stainless steel open face case with screw back and bezel, marked “Staybrite – Swiss Made” and the Zenith logo below.  The back marked with the broad Ministry arrow, stores and serial numbers.  “H.S.3” has been struck through with two lines.

A rare type of dial intended to emphasise the minutes picked out in red on the intermediate chapter ring. The outer markings calibrated to indicate 100 divisions per minute. This allowed for rapid mathematical calculations expressed in terms of decimals.
