The longest strap available with a 38mm is 200mm. My wrist measures 210mm, but I want a 38mm. I actually have a 38mm with a black classic buckle, and the last hole is just fine for me after stretching the leather a bit. I tried a 38mm milanese loop and couldn't get my hand through to put the watch on! I know there is an obvious trend that 38mm watches need shorter straps, but I think there ought to be longer options for the 38mm. Maybe third party suppliers will do this, but at the moment none of the third party suppliers quote a length. I know general thinking is that "bigger is better" but I think the 38mm with black classic looks nicely inconspicuous and doesn't shout "look I've got an apple watch!"
