·Yes I did (along with another BCT that had to be trashed) and you're right. I was lucky to get this!!
You can get an Extract from the Archives from Omega. That will tell you when the watch was shipped to a wholesaler and to which country. Omega will not "authenticate" the watch.

From your screen name I will assume you are from Australia. You can order online. Those in the USA need to go through an Omega Boutique near them.
You watch looks like a very nicely kept example. The polishing is minimal. I would recommend a search for a proper 10-sided (almost impossible to find) or scalloped (much easier to find) crown. The modern replacement is somewhat jarring to my eye. Here is @Hijak's example:
