Certain Accutron were approved to be used by American and Canadian railroad lines. The Models were all noted on the dial to be Railroad Approved or RR, all had 24 hour markings on the dial. Additionally the Canadian version had "0" in place of the "12" like this one.
At this time I would note this as a 1968 Bulova Accutron without noting a further variant or model designation, it's a very nice looking watch.
