I'm contemplating the Ultra as I have quite big wrists and even the 45mm Series 7 can look a bit small. It would have been nice if the screen had filled out more of the 49mm case size but the extra battery life will be a bonus. I also dive occasionally so that would also come in handy although not a deal breaker. Now if Noel Leeming will only update their website for pre-orders I will probably purchase. NL is the only retailer in my area that sells Apple Watch so I'm kind of stuck with them unless I want to courier from elsewhere and now that the 26th Sep is a public holiday it would likely be delayed further by a day or so.
