Did Bulova Astronaut copy design of Glycine Airman?

The Bulova Astronaut dial and bezel appear similar to the Glycine Airman's features. Since the Airman came out in 1953, it seems reasonable to think that the Bulova designers were familiar with it's design in 1960 when the Bulova Astronaut was released.

The movements are of course completely different. The lack of a crown, much less two is the most obvious visual difference. But strictly looking at design, is there any evidence that Bulova copied the successful design of the Airman? They would not be faulted for doing so. Rather, they would be building off what was already familiar and liked by pilots.

As background, I own a period Astronaut and hope to own a period (65-66) Airman someday. If biased, I have a slight bias towards Bulova since it is on my wrist. However, it sure looks similar to an Airman to my eye.

I did look for evidence before asking. This may prove that I am a poor researcher.

Just curious on a rainy Saturday at home. Looking forward to any feedback.

I was thinking the round silver bezel with black dial dominates both watches at a sweeping glance. Both bezels have notched edges, which makes sense from a form follows function perspective. Both bezels have lines between the numbers on the bezel, with the lines standing in for the odd numbers and only etched even numbers.

Both make use of round plots, although the Bulova had a couple different dials. Both had rectangular plots at 24/12 and opposite at 12/6. The latter Bulova is a bit less busy, which I like.

Both had script midway in the upper half and lower halves of the dial. Bulova had "bulova accutron" on two lines in the upper portion of the dial and Glycine had " glycine airman" in the same location.

Both had a single line of text in the lower half, with one saying ""Astronaut" and the other reading " automatic".

The early Airman did not have the broad arrow hour hand so the hands were similarly shaped.

The bigger difference to me is the hidden lugs of the Bulova, accentuating the roundness in the Bulova more so than the Airman. But there seems to be more than a passing similarity in the design. Certainly seems like the bulova referenced the airman at least.

Maybe I just have too much time on my hands...
