not being much of a Speedmaster expert what are views on this example I have the moon watch and this really took my eye
There are lots of opinions on this MB re: the Speedmaster reduced. Seems there are those that love them (me), those that have a low opinion of them, and those on the fence. If you use the search function (above), you can read many threads and many opinions. Many prefer the moon watch, but you already have one of those.
It’s not common but they made a bunch of these if that’s what your asking. It’s also a reduced speedmaster ie automatic and 40mm. They are not particularly collected.
