Fliegerchronograph ref 3741 real?

Hi, 
Please help me regarding this watch. 
What do you think, is it real? 
I see no signs of a fake watch, but my eyes are new to this. I know the strap is not original.

Very thankful for all help!

Best regards
Andreas

Looks good to me 

Thank you for answer! And it seems to be in really good condition

No issues to observe.

Thank you!

The experts already voted, but it certainly looks original from your pictures.

Kind regards,

Thank you, looking forward to wear this watch as my daily watch.
