SMP Reduced?
Not sure what size is is, but I have the regular 41/42mm and it wears small due to the thin case.
+1 for the speed master reduced
you couldn't go wrong with a 39mm Oris Aquis as well
Good luck getting a decent Speedmaster reduced for less than a £1k, they are starting to go up in value..
If you are happy with a Speedy Pro then 38mm is not your ideal size as these come in at 42mm, suits me though and I have just under 7" wrists..
