145.022 74-76 dome dial tall S drop r. In late -76 production about sept 77 the S dropped to the bottom of the p in speedmaster. The -74 has not been proven to come with a step but is currently accepted in low serial numbers as per MWO and 101. I’ve researched these heavily keeping track of serials and dial type and have not yet confirmed. I have confirmed-76 switch over.
FYI guys the step is on the minute markers not the subdials.
