Congrats on the job and the fine timepiece! It's a good looking watch from a reputable brand with a long history in racing (I know that is your thing so I think you picked the right watch), and it has a very reliable movement.
Akasnowman hit the nail on head- this is a website filled with watch enthusiasts, and we are going to have our own strong opinions. The important thing is to learn what people are saying about watches and different brands and movements but then make your own decision based on your tastes and desires. For example, one of my dream watches is a Bremont Alt1-P. It is a chronograph like yours and in fact has the same movement (a Valjoux 7750). It also retails for more than $5000 dollars. I know what people on this forum would have to say about spending that kind of money on a watch that has the same movement as their much cheaper Hamilton. But guess what? I still want the Bremont. Something about the watch or the brand or the way it looks just speaks to me. And this phenomenon is the essence of watch collecting- you need to get the thing that speaks to you. Don't just get another watch because it is cheaper or has a certain movement. Get what excites you. And, from your post, it sounds like the Carrera is a very good choice for you. So I say congratulations and enjoy the watch!
And also be careful because this can be kind of addicting. ;)
