Here's a 42mm Speedy (though not a moonwatch, it has a moonwatch case)

Here's the 39mm pre-moon on which the numbered edition is based (well, close to it and very similar to it)

My wrist is about 7.25..
The 42 is a good size, 39 feels nice too, but not as substantial. It's a very tough call. I'd probably go with 42 if I had to choose, or at least 42 first..
You can't go wrong with either though!
