Bulova Accutron Astronaut Mark II GMT

This oddity turned up in the post this morning, and despite all my efforts the closest I can find is a single example of seemingly the same model but in a different colorway. A thread on that watch describes it as being pretty rare, which given it’s the only one I can find may actually be true for once.

Can I ask if there if anyone here has ever seen this specific model before, and any recommendations for EU based watchmakers who can service a cal. 2185.

Sorry for the quick and dirty photos...


And here’s the similar one I found...

Might be a good idea... I’ll give it a go and if it gets some replies I’ll ask a mod to delete this one.
