Breitling Royal Canadian Air Force Chronograph.
One of the crowns of my collection Unsigned dial, under the radar, which is a must for a pilot watch. 
Big love for this watch which is with me for 16 years, now...
Best,

Beautiful, clean, and well preserved!
certainly not many around these days, and especially in this condition.
That is super cool.
I can understand why it’s been with you for that long. I’d never sell it either if I had one.
What a splendid pic of a sublime, fine watch !!
You have to be congratulated for this
superb tic-tac !
What a fine watch, refined yet cool as well !
Continue to enjoy it in the very Best
of your health !!

Love these RCAF monopushers.
Beautiful specimen. These had variants from the mid 60s onwards, but I am guessing yours may be 70s, just based on how incredibly good the condition looks. Not many of these left, and even fewer looking like that!
