you can get the aqua terra in (gen) 34mm, 39mm, 42mm, only the 39mm ones have been repped to a good standard, i used to have about 6 of them at the highpoint of my At collecting phase and a the gen, the 39mm rep was literlay 99% of the gen, the the railmaster, 99.8% of thhe gen, and they do not wear large.
I would sujest you get round a few jewelers and try on some gens and then come back with a better idear of what you like, also we all started looking for watches that fitted our skinny wrist, then we all bought 47mm fiddys and realised we could wear what ever we wanted.
