My wrist is 196mm in circumference. I was all set to pre order the 38mm (as I like a smaller watch) but I now fear the strap won't be long enough. I'm planning on getting SS with white sports strap (initially). According to Apples size chart - 38 mm M/L strap supports up to 200mm wrist size and 42mm M/L supports up to 210mm. This leaves only either 4mm to tuck in inside the band if I use the last hole on the band if I buy 38mm or 14mm if I buy the 42mm. Am I measuring correctly? Are Apples band sizes including when attached to the watch itself or is the size they quote (eg. 210mm) for the band minus the watch? It's all a bit confusing! I want to order on 10th April first thing before I go to work and don't have time to get to an Apple Store that day...it's a problem for those of us who want it on April 24th as it may sell out for deliveries that day, before we get a chance to go try it on and confirm our size. Maybe the strap size is just for the band? Eg. If you put the two edges of each piece together and measure the circumference. Guess we are all in the dark about this one!
