It's Speedy Tuesday! Once in a while we have guest contributors for the Speedy Tuesday topic. Today's it is Boris of the Watches and Art blog and contributor to WatchTime.net. Just recently, he also contributed to Speedy Tuesday with his wonderful Omega Speedmaster ref. 2998-61. Today, Boris contributes with a story on his Omega Speedmaster Professional 145.012, supposedly the same reference that Buzz Aldrin had in space. Although it has never been confirmed and we've seen other references for Adrin's watch as well.
