I can clear it up for you with regard to the Mako on SS. Its too small for 8in wrist without a link of 2 depending on how loose you want the bracelet.Mine is 8.25". This means that most entry-mid level Seiko autos on bracelet (with the exception of a few of their divers) are pretty much off my radar. Nothin' spoils the mood quicker for me than having to add 20-50% to the cost of the watch in extra links. Thankfullly, most of the orient divers and dress watches come with bracelets with plenty of length.
Now, this is based purely on estimates provided by product descriptions on sites like Blue Dial, Discount Watch Store, or Premierworld on the bay. I have no idea how accurate they are and frankly I've no stomach for gambling at the moment.
So many different wrist types! I amI find that most divers are a good fit without any adjustment. But I have to be careful ordering straps for my 8 1/2 inch wrist. The funny thing is I always thought my wrist small but I was comparing mine to my fathers. 9 1/2 to 10 inches, he was a big man - not fat.
