I've had a Navihawk in one form or another since my 21st birthday, when my parents bought me my original. When it took water in and couldn't be fixed after numerous attempts, Citizen stepped in and did a briliant deal on a new model. Now I've treated myself to a Titanium Red Arrows edition and... WOW! It's is SO light. I'm used to the weight of the Stainless Steel models but this is almost unnoticable on the wrist in comparison. Time keeping is, of course, brilliant with the Radio Control and never having to worry about charge (unlike my Apple Watch!) is so good. It's a beautiful piece and I use this in anger at work flying an A321. Love it!
