Greetings to fellow Ball Club members.
Correct me if I am wrong. From what I understand, 3H gas tube is where the tritium gas is being capsulated in the tube form. We have seen Ball watches featuring all various sizes, brightness and colours, but is it possible to come out with different shapes of gas 'tube'? :think:
I think it would be interesting when Ball watches can have different designs of the hour/minute/second hands, dial index etc. :p

There are already different shapes of gas tubes. Look between the Hydrocarbon series VS. The Trainmaster series.

Obie, thanks for the nice photos. :-!

What I mean was shape that is aside from the current 'tube' look. Like a triangle shape, or like the hour hand of the seiko monster that come in one piece of a gas tube.

also curious. Perhaps the tubes must be cylinder shaped for the gas or something?

I'm curious, too. I'm no engineer by any stretch of the human imagination...but I'm guessing that any shape that might be used in the design of the mineral glass tritium vials, must be structurally sound and strong enough to safely and securely contain the radioactive tritium gas, even through the unplanned minor impacts that the owner would typically subject his watch to in daily life. Perhaps the standard cylindrical shape of the vial is the strongest and most economical shape to manufacture in vast quantities...? :think:

Could it also be that some of the possible vial shapes might not be the best shapes for keeping the tritium glow evenly distributed throughout the vial? :think:

Any engineers out there? Inquiring minds, you know...

;-)

I'm not sure what the tubes look like inside my Moonglo but the numbers have some nice curves to them and they look just the same in the dark. Here's an example.
