The WOG and BOW codes are export codes. The movement manufacturer (Venus) made movements for a lot of different watch companies and they stamped the balance cock to identify the manufacturer that the watch was made for. As a general rule WOG is for Wakmann - Breitling's US distributor (wholly owned by Breitling - it was a complicated model to circumvent some US protectionist legislation) and BOW was for Breitling. However that rule doesn't really hold true, so you can't rely on it. Bottom line is that if the movement is stamped BOW or WOG then it's a movement produced for Breitling.
Ah ... makes sense. See there, I knew you would have the answer!
