Different brands, different models, but the arrow symbol is always similar. What is it? Does it denote a military-issue watch?

 

Broad arrow.

 

Also very often faked to increase value.

 

Commonly referred to as "Broad Arrow".

Thankyou for the picture ludi, now I see more background to my watch and it’s specific markings
