I have to ask....why???
It looks the hands are on the same stem, so it's technically one hand, just split to have two end points, but why?
[/quote]You are right the hands are on the same stem and I don't get it either? The only thing I can figure is there is an outer ring of black numbers and an inner ring of red numbers and when it's let's say "1 o'clock" the black "1" and the red "13" fall between the double hour hands that are black and red and depending on if it's night or day you read the time as one of the two numbers that are in between the double hour hands? It's the only thing that comes to mind?
It's an interval of some kind. 5 gradations for the hour hand is one hour, so the difference is a safety buffer? I originally thought it was a 5 minute warning, but this is the hour hand. If anyone out there is a RR worker that has worked with these, maybe they can chime in.
Over at 'Old Father Time' website they have a similar one. They state:
'This dual hand model was used by Rail Workers and those who frequently traveled between time zones.'
This was my first impression as it makes sense with the US's 4 main time zones.
Here are a few other non Bulova examples:
Time zones that were always one hour apart, That makes sense because there was no jet travel to jump across time zones.
What had me confused on my watch is the outer ring of numbers is black and the inner ring is red and the hour hand is half black and half red so I was thinking that was somehow related to each other...
Over at 'Old Father Time' website they also have an astronaut described as "Bulova Accutron 214 ASTRONAUT Dress Dial" which as far as I can tell that "dress dial" is in fact for a day/night astronaut, I think but never say never with Bulova. lol
