Hello I had my try on appointment today. I have a 38mm SS link ordered. I have a 170-5mm wrist. I have always wanted the slightly smaller watch for the less dorky look. I tried on 38mm SS link, 42mm SS link, 38mm classic buckle and 42mm classic buckle. I was wearing my Hamilton thin-o-matic black face with leather strap watch to the appointment. I also commonly wear a Casio W-49 SS (swimming, bathing kids and generally mucking around). The Apple Watch SS link is very blingy. I was wearing a t-shirt and with bare arms it is really noticeable. Definitely the right choice for me to get the 38. The 42 looked like wearing a iPhone on my arm. However with the classic buckle I could definately get away with the 42. It's much more like wearing my Hamilton - SS case and black leather strap. Blends into my arm. I'm sticking with the 38 SS link and it's the right choice for me sizewise with that strap. However I thought about changing to the classic buckle and saving myself $450 (AUD here in Sydney). Quite a price difference and arguably no better just a different look. If I was to do that I may have changed watch size to 42.
