I first encountered this "busy looking" Citizen when I sold one of my watches. The buyer was wearing a Navihawk and I remembered the blue/yellow accents. I was told this watch took a fair deal of beating and yet it still looked presentable and works perfectly! After that encounter I forgot about the Navihawk for awhile as it was never in my cross-hair.
Recently I read somewhere about a fellow WIS's Navihawk and began researching into it, in particular this Blue Angels edition (If you do not happen to know, the Blue Angels is a US Navy F-18 Hornet Aerobatic team.). It seems that the Navihawk served many wearers well over the decade of her production. Probably I should get one and find out more. Another grab-and-go weekend watch!
In my opinion, the Navihawk trademark feature is her busy dial, with digital and analog display. The presence of the sliderule bezel made it busier but probably also made her more toolish (read "professional") looking. There is a world-time function that cycles easily through the major cities.
The marketing aspect here is the unique caseback showing the Blue Angels insignia. Something different from traditional casebacks.

The C300 Caliber is a no-jewel metallic quartz movement. Note that the latest version of the Blue Angels is using the Eco-drive movement and has integrated lugs. Personally I prefer conventional quartz i.e. without the Kinetic or the Eco-drive. Simple battery works well for me when it comes to quartz calibers.
The clasp is double locking and the bracelet is of a solid stainless steel jubilee style, versatile with most outfits, any occasions.
