Browsing earlier, I noticed the O&W website has finished up selling watches branded O&W and it seems Mr Wajs is just selling off the last of his Aviation (Navitimer type) watches.
I have had three O&W watches over the years and I still have my Mirage III (best V7750 there is). I have a huge affection for those watches and that brand. At one time I ended up in regular correspondence with Mr Wajs and he is a gentleman. He is 87 years old and I wish him nothing but the best.

In the final image I compare an O&W Mirage III to a CWC G10 and a Rolex Exp 11 (40mm). The bracelet (LHS) is the one that was supplied with the Mirage III from Mr Wajs.
